I was skeptical since the source did not provide any new model name. Well it turns out this is the correct. The new model will be called the WH-ULT900N.</p><p style="text-align: justify;">Whether the model will keep using the XTRA BASS branding is unknown to me, but it could perhaps change to something like ULTRA BASS? Regardless, the model is name has changed. Not sure a model name change was necessary but perhaps Sony has their reasons. </p><p style="text-align: justify;">For those wondering the design will be a mix of the current WH-1000XM5, WH-XB910N and WH-XB700. Meaning earcups like WH-1000XM5, the hinge support like on the WH-XB910N and the headband flush with the hinge like in the WH-XB700. The feedforward NC mic mesh will be similar to the one found in the WF-1000XM5, but much larger. The colour of the mesh will be the same colour as the body.</p><p style="text-align: justify;">EDIT: Actually to simplify the description, they are closer to the design of the WH-XB900N, but without the extra vent under the hinge. <br /></p><p style="text-align: justify;">The import/export filing also confirms the new colours, black, white and gray.<br /></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhWnMqvHYySGmHFEXovMtDJpdAcgZs72m4aU_1ESqQ3oDRMYLUP3rZRQeENcPj2TBGDBUgCJTgivM6KyhGEF-nCmVflSdH6gt61hF1PUp7Z43_qRSAknZOtBLcuwN8tx9AAzSYcj8ilZWT8M9NlTjCcWmXz8v0lELINaFzOs65BGThHDx9iA3dKw2JSlbQI/s500/yy2981-WHULT900N-1.jpg" style="margin-left: 1em; margin-right: 1em;"><img alt="Sony YY2981 WH-ULT900N WHULT900N WHXB920N" border="0" data-original-height="500" data-original-width="500" height="640" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhWnMqvHYySGmHFEXovMtDJpdAcgZs72m4aU_1ESqQ3oDRMYLUP3rZRQeENcPj2TBGDBUgCJTgivM6KyhGEF-nCmVflSdH6gt61hF1PUp7Z43_qRSAknZOtBLcuwN8tx9AAzSYcj8ilZWT8M9NlTjCcWmXz8v0lELINaFzOs65BGThHDx9iA3dKw2JSlbQI/w640-h640/yy2981-WHULT900N-1.jpg" title="Sony YY2981 WH-ULT900N WHULT900N WHXB920N" width="640" /></a></div><br /><p>

The current model has a gain of -6.0 dBi, versus -4.5 dBi for the new model. This is not my field of expertise, but from my limited reading up on this, the higher the value of gain the more directional it is. Perhaps the new model antenna is an improved design and could provide better connection stability. <br /></span></p><p style="text-align: justify;"></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhjAuWuyj_dZBRl9iGN3KsfIECPcfj0eDZuK6vUJ1igHdNVnHQvT5_LMzwPyltHDaKAULxv96nat8Cw4Ox-CpyXyM3vtd3hxa-R5czdptW_wg_fHKe8CeZIqF4aHJV8YhV2RGgSKjaKBL-_r4-RoPDvTtvL38w7Nqw_aQBH6eb-sn056zSwexzu6TqqpeEw/s1136/antenna_gain.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img alt="Sony LinkBuds 2 YY2964" border="0" data-original-height="191" data-original-width="1136" height="108" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhjAuWuyj_dZBRl9iGN3KsfIECPcfj0eDZuK6vUJ1igHdNVnHQvT5_LMzwPyltHDaKAULxv96nat8Cw4Ox-CpyXyM3vtd3hxa-R5czdptW_wg_fHKe8CeZIqF4aHJV8YhV2RGgSKjaKBL-_r4-RoPDvTtvL38w7Nqw_aQBH6eb-sn056zSwexzu6TqqpeEw/w640-h108/antenna_gain.jpg" title="Sony LinkBuds 2 YY2964" width="640" /></a></div><p></p><p style="text-align: justify;"><span class="css-1qaijid r-bcqeeo r-qvutc0 r-poiln3" style="text-overflow: unset;">Finally, the short term confidentiality date ends on </span><span class="css-1qaijid r-bcqeeo r-qvutc0 r-poiln3" style="text-overflow: unset;">September 12th 2024, which could indicate a IFA announcement and then release.

like Sony asked RRA to remove the photo, along with the certification.
This is the first time I see Sony asking RRA to remove a certification. I
have posted countless of RRA certifications in the past, and never have
I seen them remove any. Perhaps the certification was not supposed to
go live just yet?</span></p><span class="css-1qaijid r-bcqeeo r-qvutc0 r-poiln3" style="text-overflow: unset;">I will be keeping an eye out for the new headset on various other certification sites, so far nothing.</span><p style="text-align: justify;"><span class="css-1qaijid r-bcqeeo r-qvutc0 r-poiln3" style="text-overflow: unset;">The certification date is from the middle of February, with the new model codenamed YY2964.

The <a href="https://amzn.to/3Ispyl2" target="_blank">WF-1000XM5</a> use YY2963, so I suspect these new LinkBuds were developed at the same time as the <a href="https://amzn.to/3Ispyl2" target="_blank">WF-1000XM5</a>.<br /></span></p><p style="text-align: left;"></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiNuSvitGblE4MxKEY1f7HwRzf4LtmIgnSuokRE-UosiqvosBVwrUUIOARpMTdAnkScW-Mn3N_uOsKRVoao-5gXEklRmkC1NoNBcaSGWcux5AjKHLSzwDhwvDF8SDEci1d2ICkS6zUx8H9dFUmRi8X62TPW9mbCJHJO4HCUsEYghuGdrHBqAIwBhFZ-q60d/s640/yy2964_02.jpg" style="margin-left: 1em; margin-right: 1em;"><img alt="Sony LinkBuds 2 YY2964" border="0" data-original-height="640" data-original-width="640" height="640" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiNuSvitGblE4MxKEY1f7HwRzf4LtmIgnSuokRE-UosiqvosBVwrUUIOARpMTdAnkScW-Mn3N_uOsKRVoao-5gXEklRmkC1NoNBcaSGWcux5AjKHLSzwDhwvDF8SDEci1d2ICkS6zUx8H9dFUmRi8X62TPW9mbCJHJO4HCUsEYghuGdrHBqAIwBhFZ-q60d/w640-h640/yy2964_02.jpg" title="Sony LinkBuds 2 YY2964" width="640" /></a></div><br /><span class="css-1qaijid r-bcqeeo r-qvutc0 r-poiln3" style="text-overflow: unset;">Very little is revealed from the certification, apart from place of manufacture, Vietnam, and the design.

Open the case and insert both earbuds into the case, keep the lid open.</p><p style="text-align: justify;"><span> </span>2. The LED should flash 3 times in orange, pause, then flash 3 times again.</p><p style="text-align: justify;"><span> </span>3. Press and hold the button on the back of the case for 15 seconds.</p><p style="text-align: justify;"><span> </span>4. When the LED flashes 3 times in orange, release the button within 5 seconds.</p><p style="text-align: justify;"><span> </span>5. The LED should flash 4 times in green to indicate that the new earbud is paired to the case.</p><p style="text-align: justify;">If the LED does not flash green, repeat the procedure from step #3. Hopefully a second attempt should pair the new earbud to the case. </p><p style="text-align: justify;">If at this point it is still not working, then the replacement earbud might be on a different firmware than your old one. As far as I know, only Sony can pair earbuds that are on different firmware versions.<br /></p><p style="text-align: justify;">I hope this guide is clear and helps anyone needing to pair a new earbud.

Now the headset has finally appeared on Bluetooth SIG, where it is described as "Wireless Stereo headset". We do know it will come with Noise Cancellation as this is how it was described in the FCC filing. so this is probably an error.<br /><span></span></p><a name='more'></a><p></p><p>Some details from the filing:</p><ul style="text-align: left;"><li>Bluetooth version is 5.2</li><li>The headset is LE Audio certified, as Isochronous Adaptation Layer is supported</li><li>The Bluetooth chip is identified as being the same one used in the LinkBuds S, Inzone H5 and Inzone Buds, meaning we are looking at the Mediatek MT2822</li></ul><p style="text-align: justify;">What we do not know, is whether the headset will support LE Audio out of the box or receive a firmware update that will add it later on. I suspect the former.<br /></p><p style="text-align: justify;">In addition, the headset has appeared on a number of import documents late last year. The descriptions are a bit off but what I can gather is that we will have 2 colours, black and white. Previously we only had black and blue with the WH-XB910N. Funny enough, it is also described as Wireless Headset without the Noise Cancellation description. Btw, the import/export filling results usually appear much later than the dates of their actual import/export.<br /></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg0HsYY8sco6hstSmv_Mp5xVQ14Yg0yGFULgh3PJTuDOnC5vqjmHsyVhJK4s2CrMqrGTpGZGsUB7U5JXtO7u_BA_dRmk4mFxF66wmR4DMtEDT2AiXi2d8gxt7OIVWHhTSayzG1fd2c_XuXbEGc5JBjNHoCC4wE08NLLE0BTq4UQSu3RcvMgDHVAE2avbHPR/s739/YY2981_import.jpg" style="margin-left: 1em; margin-right: 1em;"><img alt="Sony YY2981 WHXB920N WH-XB920N" border="0" data-original-height="739" data-original-width="667" height="640" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg0HsYY8sco6hstSmv_Mp5xVQ14Yg0yGFULgh3PJTuDOnC5vqjmHsyVhJK4s2CrMqrGTpGZGsUB7U5JXtO7u_BA_dRmk4mFxF66wmR4DMtEDT2AiXi2d8gxt7OIVWHhTSayzG1fd2c_XuXbEGc5JBjNHoCC4wE08NLLE0BTq4UQSu3RcvMgDHVAE2avbHPR/w578-h640/YY2981_import.jpg" title="Sony YY2981 WHXB920N WH-XB920N" width="578" /></a></div><p></p><p style="text-align: justify;">A few sites are quoting a post from 91mobiles, with "supposed renders" of the headset. In fact the photos are wrong and the photos are of the WH-CH720N, which they claimed last year was the WH-XB920N. They never responded to my replies in their tweets.<br /></p><p style="text-align: justify;">Even the <a href="https://www.soundguys.com/sony-wh-xb920n-106891/" target="_blank">SoundGuys reposted</a> the photos from 91mobiles, which is puzzling as they have a review of the WH-CH720N on their site, so either they tested the WH-CH720N, or they did not. I sometimes wonder if these bloggers/reviewers even analyze the content they repost.<br /></p><p style="text-align: justify;">I suspect we are inching closer to the reveal date, perhaps early to late March? Finally, we still have no news about the WH-1000XM6, so either it will be released later on in the year and the WH-1000XM5 still have some life left in them according to Sony.

</div><br />
<div style="text-align: justify;">We are at the start of a new year and that means CES. In previous years Sony has unveiled some portable Audio, like the ZX1, ZX2, and WS Walkmans. We also had the MDR-XB950 and MDR-1AM2 launch at CES in previous years. We did see the A300 and ZX700 launch after CES 2023, and recently, both received the Android 13 update, so I would not expect any new Walkmans at the show.<br /><span><a name='more'></a></span><p style="text-align: justify;">Sony will be holding their CES 2024 press conference at 5pm local time. Check the YouTube video below to see a countdown in your local timezone.</p><p style="text-align: center;"><iframe allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share" allowfullscreen="" frameborder="0" height="315" src="https://www.youtube.com/embed/PMxaYHisuIg?si=b44WNq-eSdqTn4ng" title="YouTube video player" width="560"></iframe><br /></p></div><p style="text-align: justify;">
The video hashtags do not reveal much, we will definitely see more from Sony's joint venture with Honda and their Afeela brand, that is certain.<br /></p><p style="text-align: justify;">The WH-XB920N could launch at CES, but the FCC dates indicate a launch
closer to Spring 2024. So my thinking is we should see these announced later, Spring 2024, or in the February to April timeline. Although Sony could pull a surprise at the show.<br /></p><p style="text-align: justify;">I suspect Sony will preview some of the camera tech used on the upcoming Ghostbusters film. Sony's Creator App could get some air time, maybe new features or new device support. Or it will just be mentioned by some guest how they make use of it.<br /></p><p style="text-align: justify;"><a href="https://thewalkmanblog.blogspot.com/2021/01/sony-ces-2021-preview.html" target="_blank">Back in 2021</a> during the press conference video, Sony previewed a headset which would become the <a href="https://pro.sony/en_GB/products/headphones/mdr-mv1" target="_blank">MDR-MV1</a>. So could we see a new non-wireless headset to replace the MDR-1AM2 for example? While it would be great, I do not think we will see anything. If we were to see a new high resolution lineup of headphones and Walkmans, I suspect they would get their own press conference, along with a teaser a week prior.</p><p style="text-align: justify;">I am sure we will see new TVs as is usual, perhaps finally some with LE Audio or LE Audio ready with updates later in the Spring. Along with TVs, perhaps some sound bars and wireless speakers could make an appearance at the show. </p><p style="text-align: justify;">Perhaps we will finally get a new WH-1000XM5 firmware which adds LE Audio support. </p><p style="text-align: justify;">What would you like to see at the show from Sony or in 2024 in general?<br /></p>Ascarisshttp://www.blogger.com/profile/09919961371892892332noreply@blogger.com5tag:blogger.com,1999:blog-2953732317018979267.post-44621329366119694572023-12-13T23:30:00.003-08:002023-12-13T23:30:37.758-08:00Sony A300 and ZX700 Walkmans Receive Android 13 Update<div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjG9W1Ial99zkp1KLXrBVYYwhOxt6pZsDtGY3Zjqh8PTrizL1WwzpYWLSb4_oVGQz7KHYUgZvVIUfk8sGef8hl3vlCQlpBpAbdM5KDjkYL7uMYvwh4rRK9BJxH2-nTC21qdzgCUJqnL7V3ewPlUg1VMUnloVtcAoFNgq5GqzLTna2kl5UMU-_TkgkFycDcY/s1000/A_ZX_Android_13.jpg" style="margin-left: 1em; margin-right: 1em;"><img alt="Sony NW-A300 ZX-700 Walkman Android 13 update" border="0" data-original-height="640" data-original-width="1000" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjG9W1Ial99zkp1KLXrBVYYwhOxt6pZsDtGY3Zjqh8PTrizL1WwzpYWLSb4_oVGQz7KHYUgZvVIUfk8sGef8hl3vlCQlpBpAbdM5KDjkYL7uMYvwh4rRK9BJxH2-nTC21qdzgCUJqnL7V3ewPlUg1VMUnloVtcAoFNgq5GqzLTna2kl5UMU-_TkgkFycDcY/s16000/A_ZX_Android_13.jpg" title="Sony NW-A300 ZX-700 Walkman Android 13 update" /></a></div><p></p><p style="text-align: justify;">Some great news for A300 and ZX700 owners, the Android 13 OS update has finally dropped for the Walkman models.<span></span></p><a name='more'></a><p></p><p style="text-align: justify;">Unfortunately LE Audio is not part of the update since the Bluetooth chipset was never certified for it (only up to version 5.0).

The WH-1000XM5 ear pads also cut out noise better and form a tighter seal around the ears. This has a pretty big impact on noise cancellation performance.<br /></p><p style="text-align: justify;">With the cushion over off, we can see the 30mm driver. the feedback NC mic can be seen in the center of the driver. The WH-CH720N still uses regular copper wires for the connection.

The newer model also has the entire surface sunken down creating a deeper area and space for the ear. Finally the mesh surrounding the driver is also slightly thinner. </p><p style="text-align: justify;">The WH-CH720N have no foam inside to cover the driver like the WH-1000XM5. This means only the mesh from the ear cushions will keep dust and dirt out, so in order to maintain the headset, it would be best to keep the mesh clean and dirt free.<br /></p><p style="text-align: justify;">Removing the NC mic, we can see it is an electret type microphone.</p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgwflKP1MXn7pmBLJEU9wXE-DqlScclq1Jy4_IZ5Kcq46kAkBQ78OhDiHetNWLFEhC5iuNpYS9-AKPrLry_bMrIXSPAdzLMcSw4-svmhx47jYbfJcMJBMV7AHPbq6RILGSDhfkVgAp6rsis0Z-_UgY6Xp_icUMNAZ5i6EsDCXZg5N2ssiwAXkEnngy4tw0w/s1280/whch720_tear_05.jpg" style="margin-left: 1em; margin-right: 1em;"><img alt="Sony WH-CH720N WHCH720N teardown" border="0" data-original-height="427" data-original-width="1280" height="214" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgwflKP1MXn7pmBLJEU9wXE-DqlScclq1Jy4_IZ5Kcq46kAkBQ78OhDiHetNWLFEhC5iuNpYS9-AKPrLry_bMrIXSPAdzLMcSw4-svmhx47jYbfJcMJBMV7AHPbq6RILGSDhfkVgAp6rsis0Z-_UgY6Xp_icUMNAZ5i6EsDCXZg5N2ssiwAXkEnngy4tw0w/w640-h214/whch720_tear_05.jpg" title="Sony WH-CH720N WHCH720N teardown" width="640" /></a></div><p></p><p style="text-align: justify;">This is an unfortunate revelation. From the FCC filings, it almost looked like Sony used MEMS mics, but it seems they have gone the other route and went for electret. I am sure electret mics have some advantages over MEMS mics, but recall the issues WH-1000XM4 owners had with their feedback NC mics. The high pitched noise. This was due to moisture getting into the mic and damaging it. MEMS mics are a lot more resistant to moisture and should be less susceptible to this problem. And yes, the WH-1000XM4 uses <a href="https://thewalkmanblog.blogspot.com/2020/08/sony-wh-1000xm4-teardown-by-52audio.html" target="_blank">electret mics for their NC mics</a>, only the voice microphone array uses MEMS mics.<br /></p><p style="text-align: justify;">Will moisture be an issue for the WH-CH720N and the electret mic? Good question. Hopefully it will not be an issue but in high humid areas, any problems could arise faster.<br /></p><p style="text-align: justify;">Moving on, removing the screws, we can detach the driver housing.<br /></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEioEyRevf0Ej7dlaVFzqwMI4X4_Q2uO9g4pNo1MVjnxDjbi_vdKxIVIZ2LHnluygUGl4aXdXH9z6_IPeQ1Pi56M9Xq5RgeKh2YeaU2o-fa0fWdecycPnlMk2G5k2SsBqyDg23_prOsGHZ6cwiAFSfzhpFyCnwDLdYh6l4Ik_MaDyJZroZUyNigJoEWKHwV-/s1200/whch720_tear_06.jpg" style="margin-left: 1em; margin-right: 1em;"><img alt="Sony WH-CH720N WHCH720N teardown" border="0" data-original-height="800" data-original-width="1200" height="426" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEioEyRevf0Ej7dlaVFzqwMI4X4_Q2uO9g4pNo1MVjnxDjbi_vdKxIVIZ2LHnluygUGl4aXdXH9z6_IPeQ1Pi56M9Xq5RgeKh2YeaU2o-fa0fWdecycPnlMk2G5k2SsBqyDg23_prOsGHZ6cwiAFSfzhpFyCnwDLdYh6l4Ik_MaDyJZroZUyNigJoEWKHwV-/w640-h426/whch720_tear_06.jpg" title="Sony WH-CH720N WHCH720N teardown" width="640" /></a></div><p></p><p style="text-align: justify;">On the right side, we have the battery along with the main button controls.

Some deals to be had, not huge discounts, but nice discounts nonetheless. You may be asking if the WF-1000XM5 are a safe purchase since there were battery issues with the WF-1000XM4. Good question, some reports popping up from WF-1000XM5 users saying then are experiencing issues. While it is too early to know, and too few details, I suspect that the difference in battery life users are experiencing could be from using the touch control on one side more often, which tends to drain the battery much faster. Also if the mic is set to pickup voice for the assistant, that will also drain the battery on one side.<br /></div><p style="text-align: left;"></p><p style="text-align: center;"><b><a href="https://amzn.to/49QvdxA" target="_blank">Amazon US - $248 USD</a> | <a href="https://amzn.to/3sIpnOn" target="_blank">Amazon Canada - $328 CAD</a> | <a href="https://amzn.to/3RaCa5n" target="_blank">Amazon UK - £219</a> | <a href="https://amzn.to/40QCfOS" target="_blank">Amazon De - €249</a></b></p><p style="text-align: center;"><b> </b></p><p style="text-align: left;"></p><div class="separator" style="clear: both; text-align: center;"></div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgrXRjMw2zBRrPn7CGmXkw9u7FscscgGJk16LnuaJDBnYwoIVoAXV4FW83WyhIcSxyPUs38aPkkolbsQyvg5kOklYhFNOnuW93Nwrq_4gL6yTZ5cVNCnR0ReYiRgpmGCDNIQTB-Tfx7s3HTHN7zHZrQ0uZyhXNMmy7inocaRIHXpOvyTuxlcOU50dnenhGg/s1000/wh1000xm5blkfri.jpg" style="margin-left: 1em; margin-right: 1em;"><img alt="Sony WH-1000XM5 black friday cyber monday" border="0" data-original-height="425" data-original-width="1000" height="272" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgrXRjMw2zBRrPn7CGmXkw9u7FscscgGJk16LnuaJDBnYwoIVoAXV4FW83WyhIcSxyPUs38aPkkolbsQyvg5kOklYhFNOnuW93Nwrq_4gL6yTZ5cVNCnR0ReYiRgpmGCDNIQTB-Tfx7s3HTHN7zHZrQ0uZyhXNMmy7inocaRIHXpOvyTuxlcOU50dnenhGg/w640-h272/wh1000xm5blkfri.jpg" title="Sony WH-1000XM5 black friday cyber monday" width="640" /></a></div><p style="text-align: left;"></p><p style="text-align: justify;">This will be the second Black Friday for the WH-1000XM5, so there are some great discounts and deals around.

I suspect the NC mic would still cancel noise when on a voice call. The combined NC/voice mic is also present in the LinkBuds S, so perhaps if the design worked for Sony there, this is why it was copied for the WF-1000XM5.<br /></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhw4aSmDiig7o-PMw1giF9L7lY3U0F7rh4v-g0XpAlnuIK9p3wPrglScmumqhr7NpP4Syf0WtFz7FeTTVeEHJquD-x2F4A_DYj2-WwHqH_-wCCRx9eNvL30Q5OtPOTgKrNgMjxT67y150ahvVZnPAYrIeajSB4I6ihIth_MJSnkmr0ZiacDYVfql5Fo70CR/s1100/wf1000xm5_tear_18.jpg" style="margin-left: 1em; margin-right: 1em;"><img alt="Sony WF-1000MX5 WF1000XM5 teardown" border="0" data-original-height="600" data-original-width="1100" height="350" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhw4aSmDiig7o-PMw1giF9L7lY3U0F7rh4v-g0XpAlnuIK9p3wPrglScmumqhr7NpP4Syf0WtFz7FeTTVeEHJquD-x2F4A_DYj2-WwHqH_-wCCRx9eNvL30Q5OtPOTgKrNgMjxT67y150ahvVZnPAYrIeajSB4I6ihIth_MJSnkmr0ZiacDYVfql5Fo70CR/w640-h350/wf1000xm5_tear_18.jpg" title="Sony WF-1000MX5 WF1000XM5 teardown" width="640" /></a></div><p style="text-align: left;"></p><p style="text-align: justify;">On the opposite side of the earbuds is the pressure relief hole, which is covered by a waterproof but breathable membrane.

And thanks to the INZONE buds engineer interview, we knew that battery powers both the INZONE buds and the WF-1000XM5. And now with the 52Audio teardown we have physical confirmation of the battery in the WF-1000XM5.

The bottom of the support is visible in the outlet tip. My question is, would the extra NC mic have been better as a feedforward one rather than feedback?

Sony could have perhaps used 2 mics for feedback NC and 2 mics for feedforward NC, with one mic performing voice pickup as well. </p><p style="text-align: justify;">Naturally the extra mic along with additional processing would use up more battery, so this might be why Sony only used 3 mics in total, rather than 4.<br /></p><p style="text-align: justify;">I am sure someone will eventually have 4 mics on a set of wireless earbuds, and once that happens, it will become the norm.</p><p style="text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi1_EsSTX1Zi8vIbogO6FxFoYYNHBIzjjerG77eovymIA0bElkQSG-969eNftGOXZPKM7BGczP36ZFxX28_oy1XeZYX097annvlmw_B7LvnqLilymm3GtUVptAR3564M8Sqr9mhuQf7t9UDM6XfqVcejoCUA5xmkC4sKq5-Fw1w0IhxXi0IFv0CHWCXM0Nv/s1080/sony_aff_amaz.jpg" style="margin-left: 1em; margin-right: 1em;"><img alt="Sony WF-1000XM5 WF1000XM5" border="0" data-original-height="120" data-original-width="1080" height="72" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi1_EsSTX1Zi8vIbogO6FxFoYYNHBIzjjerG77eovymIA0bElkQSG-969eNftGOXZPKM7BGczP36ZFxX28_oy1XeZYX097annvlmw_B7LvnqLilymm3GtUVptAR3564M8Sqr9mhuQf7t9UDM6XfqVcejoCUA5xmkC4sKq5-Fw1w0IhxXi0IFv0CHWCXM0Nv/w640-h72/sony_aff_amaz.jpg" title="Sony WF-1000XM5 WF1000XM5" width="640" /></a></p><p style="text-align: center;"><span style="font-size: large;"><a href="https://amzn.to/46lnPHW" target="_blank">Amazon US</a> | <a href="https://amzn.to/3G12BUV" target="_blank">Amazon Canada</a> | <a href="https://amzn.to/49s4fMG" target="_blank">Amazon UK</a> | <a href="https://amzn.to/3QG5Cie" target="_blank">Amazon Germany</a></span><i> <br /></i></p><p style="text-align: left;"><i>And now for some ranting. </i><br /></p><p style="text-align: justify;">Something that has been bugging me; it seems that Sony could have used a combination of a dynamic driver and perhaps 1 or 2 balanced armature drivers, there is space inside. Sony could have made the WF-1000XM5 slightly bigger to fit these parts in, they would still be smaller than the WF-1000XM4. Maybe this is just my flawed thinking that a mix of a dynamic driver and balanced armature drivers is better than just the one larger dynamic driver. But my XBA-A3s are my go to wired in-ear headphones almost all the time.<br /></p><p style="text-align: justify;">The counter argument can be made that with Bluetooth, the sound quality is not really there to warrant better sound quality from the earbuds. Yes we have LDAC, but even that is still lossy. <a href="https://thewalkmanblog.blogspot.com/2023/11/qualcomm-s7-pro-sound-platform.html" target="_blank">Qualcomm does have their micropower WiFi coming soon</a>, so if Sony used this or something similar in a future set of earbuds, true lossless sound could be delivered to the earbuds. With true lossless sound, the wireless earbuds would require better sound quality and perhaps a mix of dynamic and balanced armature drivers would be the ideal setup.<br /></p><p style="text-align: left;">Photo Source: <a href="https://www.52audio.com/archives/179869.html" target="_blank">52Audio WF-1000XM5 teardown</a><br /></p></div>Ascarisshttp://www.blogger.com/profile/09919961371892892332noreply@blogger.com4tag:blogger.com,1999:blog-2953732317018979267.post-61119102792995379192023-11-09T00:18:00.000-08:002023-11-09T00:18:36.796-08:00PULSE Explore Wireless Earbuds Bluetooth Certification<div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjisUoR3k4PNNrMkrUP5dud-LFgiJNKu2I3AtDslDpQsGd53yMQONY8_ccIkifKyLVjLDPgzJzRtnpZHsn5nWSmMG29Qq1paY8k2CkQxKF_faci2IUYbLkQcGGipqoUj1YKrJdcxGFWytZ7uxz-CPHw3GKuOjsRXYFeTtH6xGnLMpLa22-Mx4XwxAblhjk5/s1280/pulseexplore_1.jpg" style="margin-left: 1em; margin-right: 1em;"><img alt="PULSE Explore wireless earbuds PlayStation 5" border="0" data-original-height="720" data-original-width="1280" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjisUoR3k4PNNrMkrUP5dud-LFgiJNKu2I3AtDslDpQsGd53yMQONY8_ccIkifKyLVjLDPgzJzRtnpZHsn5nWSmMG29Qq1paY8k2CkQxKF_faci2IUYbLkQcGGipqoUj1YKrJdcxGFWytZ7uxz-CPHw3GKuOjsRXYFeTtH6xGnLMpLa22-Mx4XwxAblhjk5/s16000/pulseexplore_1.jpg" title="PULSE Explore wireless earbuds PlayStation 5" /></a></div><p></p><p style="text-align: justify;">Sony's PlayStation earbuds have passed through Bluetooth certification a few days ago, along with the larger wireless headset. While it might be a while before we see the FCC filing photos (April 22, 2024), perhaps the Bluetooth certification can provide some clues to the chipset used.<span></span></p><a name='more'></a><p></p><p>The earbuds have the combined designs, 182912,194027. The Bluetooth version is 5.3.<br /></p><p style="text-align: justify;">Both designs are found in the Sony INZONE buds and new INZONE H5 headset. Likewise the same design is used in the <a href="http://www.sunitec-cn.com/product_details/103.html" target="_blank">Sunitec BM165M Bluetooth module</a>. Even the Sony WF-1000XM5 is on this list as well.<br /></p><p style="text-align: justify;">We know that the INZONE H5 uses a Mediatek MT2822M chip, the Sunitec BM165M uses an Airoha AB1565M, the INZONE buds use Sony's own CXD3277 and its USB transceiver use the Airoha AB1565D, while the WF-1000XM5 have the Mediatek MT2833. So what chip are the PULSE Explore earbuds using? Well we have 4 options:</p><ol style="text-align: left;"><li>Airoha AB1565</li><li>Sony CXD3277 <br /></li><li>Mediatek MT2822 (V1)<br /></li><li>Mediatek MT2833 (V2)<br /></li></ol><p style="text-align: justify;">I have a write up on the <a href="https://thewalkmanblog.blogspot.com/2023/08/sony-v2-integrated-processor-deeper-look.html" target="_blank">V1 and V2 chips here</a>, but basically the V1 is the Mediatek MT2822 (or Airoha AB1568) and the V2 is the Mediatek MT2833 (or Airoha AB1588). We still do not know what the Sony CXD3277 is, but I suspect it is custom Mediatek chip for Sony. Fundamentally the MT822 is a custom/rebranded AB1565, it is technically 3 chips. I suspect the Pulse earbuds might be uing a MT2822/AB1565 chip, but we will have to wait for a full teardown to see the exact chip.</p><p style="text-align: justify;">For those wondering, the Pulse Explore earbuds are manufactured by Inventec Appliances Corp. a company from Taiwan.</p><p style="text-align: justify;">We also know the battery capacities of the the charging case and earbuds themselves. The case comes with a 3.85V 780 mAh battery (model 541963), while the earbuds use a 1454 coin cell, rated at 3.85V 105 mAh. The coin cell is from Springpower, the same company which supplies the WF-1000XM4 and WF-1000XM5 batteries. The WF-1000XM5 battery, Z55FH is 3.85V 95 mAh.<br /></p><p>Zenipower does have a 1454 Z75 coin cell, but this is 3.7V and 90mAh (0.33 Ah), so I suspect this new 105 mAh 3.85V could be a Z75H or even Z75FH.</p><p>The PULSE Explore earbuds should be released in early December, around the 6th.</p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiBRpK_bS0QttWTs6eNjROEKm5enmD1eD5Pns0V9Khmp1h0ooMezg4RXL_1WsvPRSFuZZSymcwwLATCSB1yUW4Bm6wGkUy9Wy-ug5oKtF7_FNK5Pe_oCAHUf0UvY6ITgrhyrxo7L77nhyphenhyphenY5V1ghLnSjwZCUgZrlSNpAbA_siEDlvePFg0VWPMOX7ygHtLHj/s1280/pulse_package.jpg" style="margin-left: 1em; margin-right: 1em;"><img alt="PULSE Explore wireless earbuds PlayStation 5" border="0" data-original-height="720" data-original-width="1280" height="360" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiBRpK_bS0QttWTs6eNjROEKm5enmD1eD5Pns0V9Khmp1h0ooMezg4RXL_1WsvPRSFuZZSymcwwLATCSB1yUW4Bm6wGkUy9Wy-ug5oKtF7_FNK5Pe_oCAHUf0UvY6ITgrhyrxo7L77nhyphenhyphenY5V1ghLnSjwZCUgZrlSNpAbA_siEDlvePFg0VWPMOX7ygHtLHj/w640-h360/pulse_package.jpg" title="PULSE Explore wireless earbuds PlayStation 5" width="640" /></a></div><p></p><p> If you cannot wait for the PULSE Explore earbuds, one could always pick up the INZONE buds. </p><p style="text-align: center;"><iframe frameborder="0" marginheight="0" marginwidth="0" sandbox="allow-popups allow-scripts allow-modals allow-forms allow-same-origin" scrolling="no" src="//rcm-na.amazon-adsystem.com/e/cm?lt1=_blank&bc1=000000&IS2=1&bg1=FFFFFF&fc1=000000&lc1=0000FF&t=ws-e-20&language=en_CA&o=15&p=8&l=as4&m=amazon&f=ifr&ref=as_ss_li_til&asins=B0CJHB7B59&linkId=d7e2a9544cc9fc2354a4575415ffc926" style="height: 240px; width: 120px;"></iframe> <iframe frameborder="0" marginheight="0" marginwidth="0" sandbox="allow-popups allow-scripts allow-modals allow-forms allow-same-origin" scrolling="no" src="//rcm-na.amazon-adsystem.com/e/cm?lt1=_blank&bc1=000000&IS2=1&bg1=FFFFFF&fc1=000000&lc1=0000FF&t=ws-e-20&language=en_CA&o=15&p=8&l=as4&m=amazon&f=ifr&ref=as_ss_li_til&asins=B0CJH6NV38&linkId=5b84b350bbcf9cc503c81d3fbf95a74b" style="height: 240px; width: 120px;"></iframe> /></p>Ascarisshttp://www.blogger.com/profile/09919961371892892332noreply@blogger.com0tag:blogger.com,1999:blog-2953732317018979267.post-56920502285098489002023-11-02T15:31:00.003-07:002023-12-05T19:05:54.126-08:00Qualcomm S7 Pro Sound Platform<div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjIbvuesZ8d7Ya9fF1F3OgGAcNmc8VrpHTvPOSxkMBM667w8wuCbhLQ64XM1H2usZVa9tX-3aSq-_kOAnDLA8Mq_GXm7WjGru9qK0Nl6wfNHaY5nAWEiOco-CK9dGEjJnPdMf8cDXD18IhoQ3J3g4FuzFsTbgVLzbZEdnANZWyCRjv70CNM0DLuzTCYkZP-/s1280/s7pro_1.jpg" style="margin-left: 1em; margin-right: 1em;"><img alt="Qualcomm S7 Pro Sound Platform" border="0" data-original-height="720" data-original-width="1280" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjIbvuesZ8d7Ya9fF1F3OgGAcNmc8VrpHTvPOSxkMBM667w8wuCbhLQ64XM1H2usZVa9tX-3aSq-_kOAnDLA8Mq_GXm7WjGru9qK0Nl6wfNHaY5nAWEiOco-CK9dGEjJnPdMf8cDXD18IhoQ3J3g4FuzFsTbgVLzbZEdnANZWyCRjv70CNM0DLuzTCYkZP-/s16000/s7pro_1.jpg" title="Qualcomm S7 Pro Sound Platform" /></a></div><p></p><p style="text-align: justify;">Last week Qualcomm announced a few new chipsets for wireless audio devices. In this post I will only cover the S7 Pro, as it is the most interesting in my opinion as it features WiFi connectivity at micro-power.<span></span></p><a name='more'></a><p></p><p style="text-align: justify;">Impact-Site-Verification: 8643f472-01ec-4094-8223-2820fa08b5e4 <br /></p><p style="text-align: justify;">Why is this important? Simple, Bluetooth no matter what anyone says cannot deliver true high resolution lossless audio. But with WiFi you can. Qualcomm claims the new S7 Pro chip with WiFi support can stream up to 24-bit 192Khz lossless audio. Qualcomm calls this XPAN, or Expanded Personal Area Network. But of course there is a major caveat, in order to take advantage of the WiFi in the new chipset, you will need to have a phone powered by Qualcomm's newest Snapdragon, <a href="https://www.digitaltrends.com/home-theater/qualcomm-snapdragon-sound-7-pro-micro-power-wi-fi/#dt-heading-snapdragon-sound-required" target="_blank">the 8 gen 3, or a PC with the X Elite platform</a>. <br /></p><p style="text-align: justify;">We already know Sony will have a new smartphone with the <a href="https://www.androidpolice.com/qualcomm-snapdragon-8-gen-3/" target="_blank">8 Gen 3 chipset</a>, so technically if Sony were to release a new set of wireless earbuds powered by the S7 Pro, they could make use of the XPAN feature.</p><p style="text-align: justify;">Except a lot of smartphone users will be using either previous gen hardware, or Apple hardware. Meaning none of these users could use the XPAN feature in the earbuds. But, the <a href="https://www.digitaltrends.com/home-theater/qualcomm-snapdragon-sound-7-pro-micro-power-wi-fi/#dt-heading-snapdragon-sound-required" target="_blank">Digitlatrends articl</a><a href="https://www.digitaltrends.com/home-theater/qualcomm-snapdragon-sound-7-pro-micro-power-wi-fi/#dt-heading-snapdragon-sound-required">e</a> does mention a possibility of the tech coming to devices without the Snapdragon chipset, like wireless speakers. I am hopeful but skeptical. </p><p style="text-align: justify;">The requirements for both the mobile and audio chipsets for certain features to work, is why Sony opted for Mediatek/Airoha chipsets, as they could provide what Sony required, regardless of the mobile chipset being used in the audio device (smartphone, PC, walkman).<br /></p><p>Let us have a quick look at the specifications of the new S7 Pro:</p><ul style="text-align: left;"><li>CPU - 300 Mhz</li><li>DSP - 2 x 500 Mhz</li><li>Bluetooth 5.4 support</li><li>Bluetooth LE Audio experiences, with Auracast Broadcast Audio</li><li>Music Streaming (A2DP): ~4 mA (no information for WiFi streaming)</li><li>Up to 3 mic support in earbuds</li><li>10.6 MB ram <br /></li></ul><p style="text-align: justify;">Impressive, for comparison, the V2 in Sony's WF-1000XM5, has a CPU speed up to 260 Mhz, and the DSP up to 520 Mhz. I believe the V2 (AB1588) comes with 16MB of embedded ram. But it is unknown what frequencies Sony uses on its chip, as there is no public V2 datasheet.<br /></p><p style="text-align: justify;">Sony also has their own custom chip, the <a href="https://thewalkmanblog.blogspot.com/2023/10/sony-inzone-buds-fcc-teardown.html" target="_blank">CXD3277 chip</a> found in the new INZONE buds. We do not have any information about this chip either, so we have no actual specifications, apart from codec support, LC3, and the Bluetooth version, 5.3. There is no LDAC or AAC support in this chip. The CXD3277 could be a Sony in-house chip or a very customized Airoha/Mediatek chip.<br /></p><p style="text-align: justify;">Could we see a similar WiFi streaming tech from Airoha/Mediatek? I suspect so, but so far I have not seen any new Airoha chip announcements or rumours online. The previous Airoha chipsets announced were the AB1565/68 in July 2022, so perhaps something later this year or early next. Assuming a new Airoha chip with WiFi for TWS is in the works, I do not think we will see it in earbuds first, but a larger headset like perhaps a new WH-1000XM6. Sony also has the <a href="https://thewalkmanblog.blogspot.com/2023/10/sony-yy2981-appers-on-fcc-most-likley.html" target="_blank">WH-XB920N</a> but I suspect this might re-use the V2.<br /></p><p style="text-align: justify;">The one thing I am wondering about is how much power this micro-power WiFi uses. We have a figure for the A2DP Bluetooth power consumption, around 4mA, but no figures for WiFi. I would guess that it would be more power hungry than Bluetooth but how much more? If you could only get 1 hour of listening, would it be worth it? Would love to see 3-4 hours but perhaps that is asking for too much with the current tech?<br /></p><p style="text-align: justify;">So what are people's thoughts on this WiFi in earbuds? Good idea or stick to Bluetooth? Would you as a consumer choose a non-Sony device if it offered this tech, even if said earbuds had inferior sound and NC? Or would you rather stick to better sound and NC versus true lossless streaming?<br /></p><p></p>Ascarisshttp://www.blogger.com/profile/09919961371892892332noreply@blogger.com2tag:blogger.com,1999:blog-2953732317018979267.post-19711517228337470402023-10-18T14:45:00.002-07:002023-11-09T00:19:43.230-08:00Sony INZONE Buds FCC Teardown<div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhKehrNWg_eq4du2A7VX2mskyV4VRRcaRpaJCS05dSySo-c10T63CfoGYawShSK_T9XHpexAa1nvAxn86NOlJt6i0q9-NECRUmRmKyWCiO4QR7lFaCCzf3IM4N9PDfoN3vj4iUy3RA9Ztc001AkAnvcHQOYm_d_IqysJTIDjd7fmsRtOZnZv4sKND5NLW0Q/s1280/wfg700_tear_01.jpg" style="margin-left: 1em; margin-right: 1em;"><img alt="Sony INZONE Buds Teardown WFG700N WF-G700N" border="0" data-original-height="1200" data-original-width="1280" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhKehrNWg_eq4du2A7VX2mskyV4VRRcaRpaJCS05dSySo-c10T63CfoGYawShSK_T9XHpexAa1nvAxn86NOlJt6i0q9-NECRUmRmKyWCiO4QR7lFaCCzf3IM4N9PDfoN3vj4iUy3RA9Ztc001AkAnvcHQOYm_d_IqysJTIDjd7fmsRtOZnZv4sKND5NLW0Q/s16000/wfg700_tear_01.jpg" title="Sony INZONE Buds Teardown WFG700N WF-G700N" /></a></div><p style="text-align: justify;">I am sure many of the blog's visitors noticed I did not cover the new INZONE release. This was mostly because any posts I made would have been drowned out by the coverage by the main tech sites. Besides, I do not get any review units, so I would just be reposting the press release. So instead I waited for the FCC documents to become available so I could make this teardown post. I do hope 52Audio performs a full teardown as it will be a lot more detailed than what I can present here.<span></span></p><a name='more'></a>Sony Japan does have an interview with the engineers but very little tech info is covered in the article. One small detail revealed is that the Bluetooth chip is a custom one from Sony, the L1. The chip is low voltage, high efficiency and has a reduced operating current.

It is dual side with the main Bluetooth chip shielded to minimize any outside interference. We can see one of the MEMS mics, which we saw earlier in the photo from Sony I already revealed the main wireless chip in an <a href="https://thewalkmanblog.blogspot.com/2023/07/sony-yy2977-yy2980-appear-on-bluetooth-sig-are-these-the-playstation-earbuds.html" target="_blank">earlier post</a>, but it is always good to see a physical confirmation. The chip is the CXD3277, or D3277 here. This follows the same pattern as Sony's other chips, like the S-Master HX, which is labelled as D3778 but has a model number of CXD3778.<br /></p><p style="text-align: justify;">I believe the earbuds use a dual NC mic setup (like the LinkBuds S), even though I cannot find any mention of this in any of the product pages.

The INZONE buds use a 3.86V 0.36Wh Zenipower coin cell battery. This is around 95mAh. The battery model is <b>Z55FH</b>. This is also the same battery used in the WF-1000XM5. How do I know this, well the design matches, but then Sony also revealed this in their engineer interview:</p><p></p><blockquote>At the same time, the power of the battery itself is also important. "INZONE Buds" incorporates the new high-capacity battery used in the latest completely wireless headphone flagship model "WF-1000XM5."</blockquote><p></p><p style="text-align: justify;">Unfortunately, I do not have the measurements of the battery, but by going off the FCC photos, it does look like the battery is 12mm in diameter, so matching a 12.1mm that is the industry standard. We do not have the height, so that could have changed. But if the size is the same as the Z55H, then theoretically one could buy 2 Z55FH batteries and swap them into the WF-1000XM4. This would help with battery life. <br /><br />Moving to the case battery, we have 2 suppliers, VDL and High Power. Unfortunately the FCC document only shows the capacity of the VDL battery. <br /></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjbEouWp4UHf4ULdXxeOpkhGn5-yx7EqFnihoDWT9NZjsV6cesnYSYPBXpYjB6_GUHiUIzEODvtam1CqGMU-DmAynQtul5ZnaqyChs8SXhY2pLElLeCJIHJbvC2if59Y5q5nTCfBENgywHmh-DYlVE2L5JbjGiCAmNpNEni4yf55H3GltfIobVuFHl_FiXM/s955/wfg700_tear_15.jpg" style="margin-left: 1em; margin-right: 1em;"><img alt="Sony INZONE Buds Teardown WFG700N WF-G700N" border="0" data-original-height="356" data-original-width="955" height="238" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjbEouWp4UHf4ULdXxeOpkhGn5-yx7EqFnihoDWT9NZjsV6cesnYSYPBXpYjB6_GUHiUIzEODvtam1CqGMU-DmAynQtul5ZnaqyChs8SXhY2pLElLeCJIHJbvC2if59Y5q5nTCfBENgywHmh-DYlVE2L5JbjGiCAmNpNEni4yf55H3GltfIobVuFHl_FiXM/w640-h238/wfg700_tear_15.jpg" title="Sony INZONE Buds Teardown WFG700N WF-G700N" width="640" /></a></div><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiQggKuObA_FuNgsuGKN4YH3C8JBzSlM2KHkqqEhqoPLLPVjuuPfTwAQNayvLT9rTb1-W7G8uFL8BUa3i1tcq0xavkLMHxLII8xkGij7uSql9k_sv2m2dYdzwC4VRB9ENb7AuwlObvE6GalX53aBtR2wD2C8g9B8ZOEaJCzD98YnHzIYF1hi0malHsNk6ez/s850/wfg700_tear_16.jpg" style="margin-left: 1em; margin-right: 1em;"><img alt="Sony INZONE Buds Teardown WFG700N WF-G700N" border="0" data-original-height="400" data-original-width="850" height="302" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiQggKuObA_FuNgsuGKN4YH3C8JBzSlM2KHkqqEhqoPLLPVjuuPfTwAQNayvLT9rTb1-W7G8uFL8BUa3i1tcq0xavkLMHxLII8xkGij7uSql9k_sv2m2dYdzwC4VRB9ENb7AuwlObvE6GalX53aBtR2wD2C8g9B8ZOEaJCzD98YnHzIYF1hi0malHsNk6ez/w640-h302/wfg700_tear_16.jpg" title="Sony INZONE Buds Teardown WFG700N WF-G700N" width="640" /></a></div><p></p><p>We are looking at a 3.85V 450mAh Li-ion battery, model number is 731734.

While not a complete teardown, we did discover the new Z55FH Zenipower battery, which is also used in the WF-1000XM5. We know that the INZONE buds use 2 NC microphones, and that the USB dongle uses an Airoha AB1565 chip. I suspect the Sony L1 (CXD3277) is a custom Airoha/Mediatek chip, but we will never know for certain. </p><p style="text-align: justify;">If anyone notices anything else from these photos, drop the information into the comments.<br /></p><p></p>Ascarisshttp://www.blogger.com/profile/09919961371892892332noreply@blogger.com1tag:blogger.com,1999:blog-2953732317018979267.post-62650318225384913552023-10-17T12:14:00.005-07:002024-03-07T12:01:45.466-08:00Sony YY2981 appers on the FCC, most likley the WH-XB920N (update)<div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEirlJPr66fMblWeO7cPi4kDdmW0qHWU6vhM5A3zBofeYr_lYEIYeQ_N1IHvHNAnIp7tUR9k9s57y6_nlT9qwK-hd4YkrAfzRWZ2A2fhivWSI452_IWaKKahQFszOCiO9eK4PGaqT5-svXOLsvvjZ7NqMgKNFNV-AASQjPRd2mAdk0eQk_RB0qtNbYc0FSwV/s1000/yy2981_01.jpg" style="margin-left: 1em; margin-right: 1em;"><img alt="Sony YY2981 WH-XB920N WHXB920N" border="0" data-original-height="700" data-original-width="1000" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEirlJPr66fMblWeO7cPi4kDdmW0qHWU6vhM5A3zBofeYr_lYEIYeQ_N1IHvHNAnIp7tUR9k9s57y6_nlT9qwK-hd4YkrAfzRWZ2A2fhivWSI452_IWaKKahQFszOCiO9eK4PGaqT5-svXOLsvvjZ7NqMgKNFNV-AASQjPRd2mAdk0eQk_RB0qtNbYc0FSwV/s16000/yy2981_01.jpg" title="Sony YY2981 WH-XB920N WHXB920N" /></a></div><p style="text-align: justify;">A new Sony wireless headset has appeared on the FCC, described as a "Wireless Noise Cancelling Stereo Headset", so we are probably looking at the new WHXB920N. Apart from the 2 recent INZONE announcements, the WH-XB920N is the other I was told about. But I do not have a release date but the final date in the FCC documents is April 11, 2024, so a release could be close to this date.<br /><span></span></p><a name='more'></a>The current model was announced in September 2021, with a FCC appearance in mid June 2021. This is about 15 weeks from FCC to announcement. If the new model follows a similar pattern, we could see a release in late January or early February. <br /><p></p><p style="text-align: justify;">Naturally the label photo reveals little, so we turn to the other documents. We know that the headset will feature USB Type-C, and the internal battery will be 3.85V with a capacity of 520mAh. Yet again, Sony will have 2 battery suppliers, Springpower and Chongqing VDL Electronics. The battery and capacity are identical to the <a href="https://thewalkmanblog.blogspot.com/2022/04/sony-wh-xb910n-teardown-by-52audio.html" target="_blank">old model</a>. So far we do not have any information about the Bluetooth Chip, but we could be looking at 3 options, either the MT2822, or the new MT2833, or Sony's own CXD3277 found in the INZONE buds.<br /></p><p style="text-align: justify;">That is all from the FCC filing. I suspect we will see LE Audio support in the released model, along with LDAC. Will be interesting if Sony makes the drivers smaller like they did with the WH-1000XM5. I would venture to guess we will get black and blue colour options again.<br /></p><p style="text-align: justify;">The headset was also certified in South Korea, confirming place of manufacture, China.</p><p style="text-align: justify;">One thing I would love to see fixed on the new model is the plastic, it was not the highest quality and the headset felt a bit cheap.

Perhaps, but you can buy each side individually (if you can find a local supplier), so I guess this should not be an issue. <br /></p><table cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto; margin-right: auto; text-align: left;"><tbody><tr><td style="text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhdQh2qggTW7iIE9N4LjGTfsYHPjLqVQCAX56pemHmC0B1VwAiDGUfZLgiKJPFgXI99dEWmctSoImN_ExQ6jDSeOwB32jaLHmcJzdzsxwRNPxP6dRy7TD9FYI4TtMUJopMUTT0aeFc0uAO5N_omRktEJsyrrSlr_BFcWkco4tRtDAnoZiPB1KH5oXROitGF/s1600/wh1000xm5_tear_003.jpg" style="margin-left: auto; margin-right: auto;"><img alt="Sony WH-1000XM4 earpads" border="0" data-original-height="800" data-original-width="1600" height="320" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhdQh2qggTW7iIE9N4LjGTfsYHPjLqVQCAX56pemHmC0B1VwAiDGUfZLgiKJPFgXI99dEWmctSoImN_ExQ6jDSeOwB32jaLHmcJzdzsxwRNPxP6dRy7TD9FYI4TtMUJopMUTT0aeFc0uAO5N_omRktEJsyrrSlr_BFcWkco4tRtDAnoZiPB1KH5oXROitGF/w640-h320/wh1000xm5_tear_003.jpg" title="Sony WH-1000XM4 earpads" width="640" /></a></td></tr><tr><td class="tr-caption" style="text-align: center;">Sony WH-1000XM4 earpads</td></tr></tbody></table><p style="text-align: left;"></p><p style="text-align: justify;">So with the earpads removed, we can see the foam which covers the 30mm drivers.

The cover looks to be made out of silicone rubber material. WH-1000XM4 users have reported a loud high pitched noise from one side and removing this cover sometimes fixes that. This noise may be due to moisture build up and damage on the mic and wires. Maybe this new design has fixed this.

According to 52Audio, there is a fuse on the board (chip with #1, by the port), this is missing in the WH-1000XM4. The fuse is a self-healing variety, so when tripped, it will revert back into a functioning fuse.</p><p style="text-align: justify;">Another change is that the ribbon cable is glued into the board with some kind of resin or something. Supposedly this is to secure the cable. This glue will make it pretty much impossible to remove the cable. If the USB port breaks, the entire PCB with the cable will need replacing. The other end of the cable is not glued into place, so it can be easily disconnected and this PCB removed.<br /></p><p style="text-align: left;">Removing the battery enclosure, we can see the back of the driver.</p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiR293dEsGDhLhUo4NhxQ4r0NC_mVJIyvqDGQ1HMOq8RsupbMP7Ma3CO2M36r2uH_j3xjmC1Mw1PyeI2Z15ub0PGt92Ijc9NFKZ2mAxCFvEA-xoXhHpX_lw0i9I3qupLYTrzuwPJ-TnpDSx7CJ9ag2vmMx9FXByV2xgVYELr8EZzmXInxSWvv9nh2PoIc2v/s1350/wh1000xm5_tear_023.jpg" style="margin-left: 1em; margin-right: 1em;"><img alt="Sony WH-1000XM5 Teardown" border="0" data-original-height="1350" data-original-width="1200" height="640" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiR293dEsGDhLhUo4NhxQ4r0NC_mVJIyvqDGQ1HMOq8RsupbMP7Ma3CO2M36r2uH_j3xjmC1Mw1PyeI2Z15ub0PGt92Ijc9NFKZ2mAxCFvEA-xoXhHpX_lw0i9I3qupLYTrzuwPJ-TnpDSx7CJ9ag2vmMx9FXByV2xgVYELr8EZzmXInxSWvv9nh2PoIc2v/w568-h640/wh1000xm5_tear_023.jpg" title="Sony WH-1000XM5 Teardown" width="568" /></a></div><p style="text-align: left;"></p><p style="text-align: justify;">The red arrows point out what appears to be (in my mind) hot glue or some kind of rubber seal which prevents moisture and dust ingress and seals the back of the driver unit from the outside.

On a side note, <a href="https://www.techinsights.com/products/bfr-2112-801" target="_blank">TechInsights</a> has a teardown of the MT2822 in a report, but contacting them on Twitter yielded no replies, and since you need a corporate email to use the website contact, that option is out as well.<br /></p><p style="text-align: justify;">So I will stick with what facts I have gathered. From the Bluetooth certification, we have information which suggested that the V2 was the Mediatek MT2833. Well thanks to the FCC filing, we can confurm this finally. If that was not enough, an additional confirmation from a <a href="https://www.ift.org.mx/usuarios-y-audiencias/equipos-sony" target="_blank">Mexican certification</a>, also reveals the MT2833 as the main chip.<br /></p><table cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto; margin-right: auto; text-align: left;"><tbody><tr><td style="text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhQTvTrnqwBNCI8s_0o95YhZZSZnftN9ZVVwba5EjSG33fAPF4GZw19L3Fg42SDqAni8BYx26zGLpmfRrGf43CH5Qzokw5w7CnXeTT13V4nlGw5mKDRmOe3sXbuu_efGMHx0yssbQTm9MiMLlqs-NZckbRCC1vNog7Hsk3ZdpC1nfdjs_UBYN9jJn0NURte/s1162/yy2963_mexico.jpg" style="margin-left: auto; margin-right: auto;"><img alt="Sony WF-1000XM5 Mediatek MT2833 V2" border="0" data-original-height="128" data-original-width="1162" height="70" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhQTvTrnqwBNCI8s_0o95YhZZSZnftN9ZVVwba5EjSG33fAPF4GZw19L3Fg42SDqAni8BYx26zGLpmfRrGf43CH5Qzokw5w7CnXeTT13V4nlGw5mKDRmOe3sXbuu_efGMHx0yssbQTm9MiMLlqs-NZckbRCC1vNog7Hsk3ZdpC1nfdjs_UBYN9jJn0NURte/w640-h70/yy2963_mexico.jpg" title="Sony WF-1000XM5 Mediatek MT2833 V2" width="640" /></a></td></tr><tr><td class="tr-caption" style="text-align: center;">Mexican Certification</td><td class="tr-caption" style="text-align: center;"> </td><td class="tr-caption" style="text-align: center;"> </td><td class="tr-caption" style="text-align: center;"><br /></td><td class="tr-caption" style="text-align: center;"><br /></td><td class="tr-caption" style="text-align: center;"><br /></td><td class="tr-caption" style="text-align: center;"><br /></td><td class="tr-caption" style="text-align: center;"><br /></td><td class="tr-caption" style="text-align: center;"><br /></td><td class="tr-caption" style="text-align: center;"><br /></td><td class="tr-caption" style="text-align: center;"><br /></td><td class="tr-caption" style="text-align: center;"><br /></td><td class="tr-caption" style="text-align: center;"><br /></td><td class="tr-caption" style="text-align: center;"><br /></td></tr></tbody></table><div class="separator" style="clear: both; text-align: center;"></div><div class="separator" style="clear: both; text-align: center;"></div><div class="separator" style="clear: both; text-align: center;"></div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgjJYIx-Vrwujcob3vngHBUdlbwqD94yH1gJMrcX9shl_xDzMkc8vCPn6WUe3EPUm3xOehGKF_YRbp7NOPFxb7McUce2CAjkMD9T-gSGuET0FifT1dm9Od2oFpr14HfYMiRbk_tpLjCr4DiMZdLUCBZbTqubaA92ZtCYDf9Tu9fRGuLMJu8NIUG39GA6USW/s1280/sony_V2_mt2833.jpg" style="margin-left: 1em; margin-right: 1em;"></a><table align="center" cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto; margin-right: auto;"><tbody><tr><td style="text-align: center;"><img alt="Sony V2 Integrated Processor Mediatek MT2833" border="0" data-original-height="786" data-original-width="1280" height="394" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgjJYIx-Vrwujcob3vngHBUdlbwqD94yH1gJMrcX9shl_xDzMkc8vCPn6WUe3EPUm3xOehGKF_YRbp7NOPFxb7McUce2CAjkMD9T-gSGuET0FifT1dm9Od2oFpr14HfYMiRbk_tpLjCr4DiMZdLUCBZbTqubaA92ZtCYDf9Tu9fRGuLMJu8NIUG39GA6USW/w640-h394/sony_V2_mt2833.jpg" style="margin-left: auto; margin-right: auto;" title="Sony V2 Integrated Processor Mediatek MT2833" width="640" /></td></tr><tr><td class="tr-caption" style="text-align: center;">FCC certification<br /></td></tr></tbody></table><div style="text-align: center;"></div></div><p style="text-align: left;"></p><p style="text-align: justify;">Introducing the GSBR-0002, the new SiP in the WF-1000XM5.

Naturally looking for any information about this chip yields very little, with most of the results from my own blog (hehe). From past and recent documentation, I have been able to ascertain that the MT2833 is either a custom or rebranded Airoha AB1588. Here is how I came to this conclusion.<br /></span></p><p style="text-align: justify;"><span>There are no product pages for the AB1588, but we do have one for the <a href="https://www.airoha.com/products/p/UATZlIz8hZq3TDky" target="_blank">AB1585</a>. But are these the same chip? I was re-reading a discussion I had on <a href="https://www.reddit.com/r/AirReps/comments/llqj84/airoha_ab1565_and_ab1568_series_the_next_big/" target="_blank">reddit 2 years ago about the MT2811</a> and I finally realized what the person was referring to. I said that the MT2811 was the AB155X, but the user told me, that was odd since there are 6, yes 6, AB155x chipsets.</span></p><p style="text-align: left;"></p><table cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto; margin-right: auto; text-align: left;"><tbody><tr><td style="text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiOL7Aff8lii9b1BkCa1BP21GMUQUsLjmjxXKucjSubXAVK1ComnQuUQFlJbvPe8BTvx0HJ5lHGNtmF1-adi6PoEoAwtSa7D5U4fu8am6NQbSRNO_t4MCc1wAI3AwJzwFz2l6Mauz1_Xl5WZ9Q58DxnIfkWrtOD5Nt-CCLv39XqjrFEJjnVAGeG2KZmy8mU/s759/ab155x.jpg" style="margin-left: auto; margin-right: auto;"><img alt="Airoha AB155x chipsets" border="0" data-original-height="607" data-original-width="759" height="512" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiOL7Aff8lii9b1BkCa1BP21GMUQUsLjmjxXKucjSubXAVK1ComnQuUQFlJbvPe8BTvx0HJ5lHGNtmF1-adi6PoEoAwtSa7D5U4fu8am6NQbSRNO_t4MCc1wAI3AwJzwFz2l6Mauz1_Xl5WZ9Q58DxnIfkWrtOD5Nt-CCLv39XqjrFEJjnVAGeG2KZmy8mU/w640-h512/ab155x.jpg" title="Airoha AB155x chipsets" width="640" /></a></td></tr><tr><td class="tr-caption" style="text-align: center;"><a href="http://www.crysound.com/news/details/224.html" target="_blank">Source</a> (link may not work anymore)<br /></td></tr></tbody></table><span><p style="text-align: justify;">While not all 6 are present in this table, we have most of them. Recall this <a href="https://thewalkmanblog.blogspot.com/2019/10/mediatek-mt2811-new-bluetooth-chip-in.html" target="_blank">post from 2019</a> about the Mediatek MT2811. In that post, I calculated the size of the MT2811 to 4.8mm x 4.8mm. We have 2 chips in that table that match this size, the AB1555A and AB1555. The only different between these 2 chips is the noise cancellation, one is TWS hybrid and the other feed-forward. Likewise notice that both need external flash for memory, which is what we had in the WF-1000XM3 <span>(Q128FWY)</span>. So I am guessing the MT2811 is just the AB1555A.</p></span><p style="text-align: left;"></p><p style="text-align: justify;"><span>But what does this have to do with the MT2833? Well we can see Airoha has many chip lines and then different versions of each chip in that line.

In the same now removed post on LinkedIn, which detailed the MT2833 as the AB1588, the MT2822 was together with the AB1568. Out of all those 3 chips, only one is square like the MT2822 and that is the AB1568. </span></div><p style="text-align: justify;"></p><p style="text-align: justify;"><span>An interesting revelation from this table is that the AB1568 is more efficient than the other 2 chips. While I have not seen any such tables for the AB158X line, we might only have 2 chips in the line up from what we can see on the <a href="https://www.airoha.com/products/p/UATZlIz8hZq3TDky" target="_blank">Airoha website</a>. The embedded flash can be either 8MB or 16MB, and from the 156X line, we can see that the AB1565 is 4MB and the AB1568 is 8MB. So I am going to go out on a limb and say the AB1588 is the 16MB version of the AB1585. This would mean the new V2 chip is a rebranded/custom version of the AB1588. The 16MB might be what Sony requires for their storage needs, as both the WF-1000XM3 and WF-1000XM4 used 16MB external flash chips.<br /></span></p><p style="text-align: justify;">With the chip now identified, let us take a look at its specifications and compare it to the V1 (AB1568).</p><p style="text-align: left;"></p>

</table><p style="text-align: justify;">The chips are relatively similar, we do not have any power consumption figures for the AB1588, so unknown if it is more energy efficient. The host processors are also different. The AB1588 uses the AMR Cortex-M33F which has 20% more performance than the ARM Cortex-M4. The DSP processor is also newer on the V2, sporting the latest design.</p><p style="text-align: justify;">Next major difference is the presence of LE Audio on the new chip, something absent in the V1. But we know the V1 (MT2822) supports LE Audio since the LinkBuds S support it and the WH-1000XM5 should also be receiving an <a href="https://thewalkmanblog.blogspot.com/2023/04/sony-wh-1000xm5-and-linkbuds-s-le-audio-coming-soon.html" target="_blank">update in the future</a>. Finally the V2 has AI noise suppression, where as the V1 only has beamforming noise suppression.</p><p style="text-align: justify;">I am uncertain if the AI functionality occurs in real time, perhaps it is only for calls? </p><p style="text-align: justify;">So there we have it. The new V2 is either a rebranded or custom AB1588. There improvements over the original V1, like newer DSP and hot processor, but we still do not know if it is more energy efficient<b>.</b></p><p style="text-align: justify;">As for the question why did Sony switch to the new chip, well, I suspect Sony wanted the AI capabilities of the chip. Whether the new V2 also has the old QN1e integrated into it, is unknown, but I would venture to guess it does going by its specifications. Another reason for the switch could be power consumption. While I have no evidence, I suspect the V2 is more energy efficient and might even be built on a newer process. Of course with Sony or Mediatek not revealing anything, we will never know anymore details.</p><p style="text-align: center;"><iframe frameborder="0" marginheight="0" marginwidth="0" sandbox="allow-popups allow-scripts allow-modals allow-forms allow-same-origin" scrolling="no" src="//ws-na.amazon-adsystem.com/widgets/q?ServiceVersion=20070822&OneJS=1&Operation=GetAdHtml&MarketPlace=US&source=ss&ref=as_ss_li_til&ad_type=product_link&tracking_id=thew017-20&language=en_US&marketplace=amazon&region=US&placement=B0C345M3T7&asins=B0C345M3T7&linkId=4d939b75e1b65b0aeb1e14ba043405bd&show_border=true&link_opens_in_new_window=true" style="height: 240px; width: 120px;"></iframe> <iframe frameborder="0" marginheight="0" marginwidth="0" sandbox="allow-popups allow-scripts allow-modals allow-forms allow-same-origin" scrolling="no" src="//rcm-na.amazon-adsystem.com/e/cm?lt1=_blank&bc1=000000&IS2=1&bg1=FFFFFF&fc1=000000&lc1=0000FF&t=ws-e-20&language=en_CA&o=15&p=8&l=as4&m=amazon&f=ifr&ref=as_ss_li_til&asins=B0C345M3T7&linkId=3a39ec432768ffa41df18742076c59ce" style="height: 240px; width: 120px;"></iframe> <iframe frameborder="0" marginheight="0" marginwidth="0" sandbox="allow-popups allow-scripts allow-modals allow-forms allow-same-origin" scrolling="no" src="//ws-eu.amazon-adsystem.com/widgets/q?ServiceVersion=20070822&OneJS=1&Operation=GetAdHtml&MarketPlace=GB&source=ss&ref=as_ss_li_til&ad_type=product_link&tracking_id=walkmanblog00-21&language=en_GB&marketplace=amazon&region=GB&placement=B0C4TJXPNJ&asins=B0C4TJXPNJ&linkId=053ee5b1934dae12df5ba53543a7b952&show_border=true&link_opens_in_new_window=true" style="height: 240px; width: 120px;"></iframe> <iframe frameborder="0" marginheight="0" marginwidth="0" sandbox="allow-popups allow-scripts allow-modals allow-forms allow-same-origin" scrolling="no" src="//ws-eu.amazon-adsystem.com/widgets/q?ServiceVersion=20070822&OneJS=1&Operation=GetAdHtml&MarketPlace=DE&source=ss&ref=as_ss_li_til&ad_type=product_link&tracking_id=walkmanblog04-21&language=en_GB&marketplace=amazon&region=DE&placement=B0C4TJXPNJ&asins=B0C4TJXPNJ&linkId=60f651d2e54ac37456a814a0588107e6&show_border=true&link_opens_in_new_window=true" style="height: 240px; width: 120px;"></iframe><br /></p><p style="text-align: left;"><b>FCC Teardown</b></p><p style="text-align: justify;">With the V2 chip identified, we can have a view at the FCC internal photos.

The small chip in the middle between is still not labelled and unknown. One thing I noticed is that there is a small difference in the design, which I have pointed out with arrows. The traces are a bit different from left to right, not sure why. Maybe it is for the manufacturing in order to be able to identify the sides? Anyone know why this is the case?<br /></p><p style="text-align: left;">The next photo shows the reverse side.</p><p style="text-align: left;"></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjLbJmXS4Uw9o8juVKYvuJTD5UPZF0tP-k44vPxCLUneIaAbY2fVya7oAlcnEKMJD_-boNU6HHJvq5FdYKtTS6QmqzjAYF_vyPILYkcabz182PvJDG7jdl1vKOc2MiUP1NM2LjwL6NbWUrq-8f3GsiLnnuXdTzCsEfg8BzhEtxWocQjzIMXrtq6B76kiW1M/s1019/wf1000xm5_teardown_04.jpg" style="margin-left: 1em; margin-right: 1em;"><img alt="Sony WF-1000XM5 WF1000XM5 teardown" border="0" data-original-height="644" data-original-width="1019" height="404" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjLbJmXS4Uw9o8juVKYvuJTD5UPZF0tP-k44vPxCLUneIaAbY2fVya7oAlcnEKMJD_-boNU6HHJvq5FdYKtTS6QmqzjAYF_vyPILYkcabz182PvJDG7jdl1vKOc2MiUP1NM2LjwL6NbWUrq-8f3GsiLnnuXdTzCsEfg8BzhEtxWocQjzIMXrtq6B76kiW1M/w640-h404/wf1000xm5_teardown_04.jpg" title="Sony WF-1000XM5 WF1000XM5 teardown" width="640" /></a></div><p style="text-align: left;"></p><p style="text-align: left;">Again, some minor differences in the layout of the traces, no idea why.

For a description of the various parts, see my <a href="https://thewalkmanblog.blogspot.com/2023/07/sony-unveils-the-new-wf-1000xm5.html" target="_blank">WF-1000XM5 post</a>.</p><p style="text-align: justify;">Here is one more shot from the FCC filing, showing the antenna, along with some measurements of the earbuds.</p><p style="text-align: left;"></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhpHHjHzvFTe3sDsAT-n5IsggKTz4b0Z7jc6aLsj5h6w9r0Gr-ZXHIQWiAvAIb9PCliNd_AYNpxnhNW0ZuWGpSOG_cQrm1CSXQv1u02Z-_I6ARWu_KWO8gBCLb0kJBkErJoU0IfR__KS0kCx3aP3Nn8dU2FDss0IGsu-poDZgI102tDf19SRoH_hTzfYA1O/s800/wf-1000xm5_fcc_dimensions.jpg" style="margin-left: 1em; margin-right: 1em;"><img alt="Sony WF-1000XM5 WF1000XM5 teardown" border="0" data-original-height="800" data-original-width="800" height="640" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhpHHjHzvFTe3sDsAT-n5IsggKTz4b0Z7jc6aLsj5h6w9r0Gr-ZXHIQWiAvAIb9PCliNd_AYNpxnhNW0ZuWGpSOG_cQrm1CSXQv1u02Z-_I6ARWu_KWO8gBCLb0kJBkErJoU0IfR__KS0kCx3aP3Nn8dU2FDss0IGsu-poDZgI102tDf19SRoH_hTzfYA1O/w640-h640/wf-1000xm5_fcc_dimensions.jpg" title="Sony WF-1000XM5 WF1000XM5 teardown" width="640" /></a></div><div style="text-align: justify;">Finally, there is one a point in the reference guide from the FCC, about charging. It says to use a charger that only delivers up to 13W. This is the same amount as other earbud model guides from the FCC. But when I compared the WF-C700N reference guides from the FCC and the support pages, the 13W warning was gone. This is interesting, but puzzling. I guess all the earbud models can handle more wattage, as the cases would only draw what they need. Perhaps the FCC reference guides are only for the test models which might be prototypes or pre-production units. Perhaps someone has an idea.<br /></div><p style="text-align: justify;"></p><p style="text-align: justify;">Well that concludes the teardown and the post. Maybe 52Audio will perform a teardown in the future, if not, I would love to do one but would have to save up money for 2 models, one to use and one for a teardown. There is little money Google Adsense and Amazon pull in, so it will be a while before I can buy anything,<br /></p><p style="text-align: center;"><iframe frameborder="0" marginheight="0" marginwidth="0" sandbox="allow-popups allow-scripts allow-modals allow-forms allow-same-origin" scrolling="no" src="//ws-na.amazon-adsystem.com/widgets/q?ServiceVersion=20070822&OneJS=1&Operation=GetAdHtml&MarketPlace=US&source=ss&ref=as_ss_li_til&ad_type=product_link&tracking_id=thew017-20&language=en_US&marketplace=amazon&region=US&placement=B0C33XXS56&asins=B0C33XXS56&linkId=e6c12a8acff33da83898d5395193939d&show_border=true&link_opens_in_new_window=true" style="height: 240px; width: 120px;"></iframe> <iframe frameborder="0" marginheight="0" marginwidth="0" sandbox="allow-popups allow-scripts allow-modals allow-forms allow-same-origin" scrolling="no" src="//rcm-na.amazon-adsystem.com/e/cm?lt1=_blank&bc1=000000&IS2=1&bg1=FFFFFF&fc1=000000&lc1=0000FF&t=ws-e-20&language=en_CA&o=15&p=8&l=as4&m=amazon&f=ifr&ref=as_ss_li_til&asins=B0C33XXS56&linkId=093176f4220091e409d6f11e635ce93b" style="height: 240px; width: 120px;"></iframe> <iframe frameborder="0" marginheight="0" marginwidth="0" sandbox="allow-popups allow-scripts allow-modals allow-forms allow-same-origin" scrolling="no" src="//ws-eu.amazon-adsystem.com/widgets/q?ServiceVersion=20070822&OneJS=1&Operation=GetAdHtml&MarketPlace=GB&source=ss&ref=as_ss_li_til&ad_type=product_link&tracking_id=walkmanblog00-21&language=en_GB&marketplace=amazon&region=GB&placement=B0C4TLFZSZ&asins=B0C4TLFZSZ&linkId=d2c800fb5e989159cf1216a0edea080d&show_border=true&link_opens_in_new_window=true" style="height: 240px; width: 120px;"></iframe> <iframe frameborder="0" marginheight="0" marginwidth="0" sandbox="allow-popups allow-scripts allow-modals allow-forms allow-same-origin" scrolling="no" src="//ws-eu.amazon-adsystem.com/widgets/q?ServiceVersion=20070822&OneJS=1&Operation=GetAdHtml&MarketPlace=DE&source=ss&ref=as_ss_li_til&ad_type=product_link&tracking_id=walkmanblog04-21&language=en_GB&marketplace=amazon&region=DE&placement=B0C4TLFZSZ&asins=B0C4TLFZSZ&linkId=cdd96eed8164c895c859875519da6bf2&show_border=true&link_opens_in_new_window=true" style="height: 240px; width: 120px;"></iframe>

With the WF-1000XM5 finally revealed, I wanted to create an in-depth analysis of the design, features and do a comparison with the WF-1000XM4. This is not a review, but I hope to have one in the future once I buy it. But I will need to save up before that happens. So let us dive in.<span></span><br />

<p style="text-align: justify;">
The most obvious change is the new design. Sony has drastically reduced the
new mark 5's size and weight. We are looking at 25% smaller size and 20% less
weight (5.9g per earbud, 39 grams for case). The size reduction will be
welcome by many, including myself. The WF-1000XM4 can become uncomfortable
after an extended period of time in my experience so I expect this issue may
have been solved with the new design. <br />
</p>
<p style="text-align: left;"></p>
<div class="separator" style="clear: both; text-align: center;">

</div>
<p style="text-align: justify;">
Aside the size and weight changes, the new glossy design will split some
opinions. When I first saw the original certification photos back in March, I
was hoping the materials would change for the final production unit. But this
turned out not to be the case. A common remark is that they look cheap, and I get that, but from my own experience with the WF-1000XM4, it can get dirty and cleaning the matte plastic can be a hassle. Now with the new model, the area that touches the ear is glossy and should be easier to clean. Of course that appears to be the idea. Whether this is true in practice remains to be seen. Of course I will still need to see in person to make a final judgement. I wonder if we could see a similar design change with the WH-1000XM6 when it
arrives next year.
</p><p style="text-align: left;"></p>
<p style="text-align: justify;">
For a size comparison, Sony has provided us with a nice set of reference
images on their product pages. In the photo below we have the WF-1000XM5,
LinkBuds S, and WF-C700N. I used the ear mesh as my size reference. <br />

</div>
<p style="text-align: justify;">
This comparison shows that the mark 5 is more or less the same size as the
other 2 and has a similar ear tip orientation like the WF-C700N. So if
you own either the LinkBuds S or WF-C700N, the new WF-1000XM5 should have a
similar fit and comfort. This is good news for me, since the WF-C700N is
really comfortable, even for long listening sessions.</p><p style="text-align: justify;">Finally here is a comparison of the WF-1000XM3 and WF-1000XM5 from the <a href="https://twitter.com/SonyStoreGinza/status/1683690033231060992" target="_blank">Sony Store Ginza Twitter account</a>.</p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhlnaLmPsn31C9qkgJzc1Ix34j3NNBpXQvcXfdTnUu3eAxNfW7DTpxIbK0kH09WHuam-Gy0kLa8WrqFx2Hcl5KDcnjKeKDV86YG71sbJdGCVJTd3vRg0-86wJJNfUgbqNyDEeWsWH47JLD2_3PQ5Jz2GbT276pgAhrMH4F52qK06u3WWNdhzpJw2ovHOKJ4/s1000/wfmk3vsmk5.jpg" style="margin-left: 1em; margin-right: 1em;"><img alt="Sony WF-1000XM3 vs WF-1000XM5" border="0" data-original-height="640" data-original-width="1000" height="410" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhlnaLmPsn31C9qkgJzc1Ix34j3NNBpXQvcXfdTnUu3eAxNfW7DTpxIbK0kH09WHuam-Gy0kLa8WrqFx2Hcl5KDcnjKeKDV86YG71sbJdGCVJTd3vRg0-86wJJNfUgbqNyDEeWsWH47JLD2_3PQ5Jz2GbT276pgAhrMH4F52qK06u3WWNdhzpJw2ovHOKJ4/w640-h410/wfmk3vsmk5.jpg" title="Sony WF-1000XM3 vs WF-1000XM5" width="640" /></a></div><p style="text-align: justify;"><b>Charging Case </b><br /></p>

Comparing the designs, we can see the new case is a lot more rounded with softer edges. The interview reveals that the inside of the WF-1000XM4 lid
is made from resin, where as in the new model, this same part is made from
silicone, which helps protect the earbuds.<br />

<p style="text-align: justify;">
The rear of the case also has a pairing button like the LinkBuds S and
WF-C700N. Wireless charging is still present, and uses the Qi standard. From reviews online,
and even in these press photos, the colour of the case (and earbuds) appears to be a
slightly different colour. I think it is the same black as the WH-1000XM5.

<p style="text-align: left;"><b>New Earbud Tips</b><br /></p>
<div style="text-align: justify;">
Another change are the earbud tips. Sony describes them as "<i>Noise Isolation Earbud Tips</i>" and says they are made from an exclusive material which enhances the fit
but also comfort thanks to their newly designed shape.
</div>
<div style="text-align: justify;"> </div>
<div style="text-align: justify;">
The new tips appear to have a similar construction to previous ones found in
the WF-1000XM4. We have a silicone center layer surrounded by the polyurethane
foam. The foam is much thinner on the bottom which should permit a better
squeeze and fit in the ear canal.
</div>
<div style="text-align: justify;"><br /></div>
<div style="text-align: justify;">
In addition Sony has included a mesh in the opening to keep out dirt and grime
from the inside of the earbuds. This mesh will require cleaning, so it will be
interesting how well it stands up to constant cleaning.
</div>
<div style="text-align: justify;"> </div>
<div style="text-align: justify;"> </div>
<div style="text-align: justify;">
We have the new model name of the ear tips, EP-NI1010. The new tips will be
available starting September 1st in Japan. No word if they will be sold
outside of Japan. The tips will be sold in individual sizes, priced around
2000 yen each. The WF-1000XM5 will ship with 4 sizes of tips, SS, S, M, and L.
The previous tips, EP-NI1000, are already discontinued. I will be buying up a
few pairs of the new tips for my WF-1000XM4 and WF-C700N, to test them out later this year. I do not expect a
huge improvement in sound quality but hopefully the comfort and seal will improve.<br /></div>
<div style="text-align: justify;"><br /></div>
<div style="text-align: justify;">
<b>New Features added to the list<br /></b>
</div>
<div style="text-align: justify;"><br /></div>
<div style="text-align: justify;"> The new WF-1000XM5 brings a few new features like gesture control and head
tracking. With gesture control you can nod your head to answer a call or shake
it to deny the call. The head tracking will be used for various applications
like 360 Reality Audio or TIDAL. But the functionality will require a firmware
update as it will be available Summer 2023. This could mean, August, or it
could be early September. Head tracking was recently added to the <a href="https://thewalkmanblog.blogspot.com/2023/07/sony-wh-1000xm5-firmware-update-version-2-0-2.html" target="_blank">WH-1000XM5 via a firmware update</a>.<br /></div>

</div>
<br />
</div>
<div style="text-align: justify;">
The updated Sony headphone app also has a new feature called "Find your
Equalizer". You play a song you like in the player, go back to the app, then click Find your equalizer. With the song playing, you have 5 EQ settings to choose from, which you can preview by selecting them. Once you find one you like, you click next, this is repeated 2 more times. At the end, you can see compare the selected EQ with your previous settings. The app is meant to optimize the EQ to a person's listening style. The feature is still in beta and it does work well. It choose a pretty close EQ to what I was using for my WF-1000XM4. I expect the feature will improve with time.<br /></div>
<div style="text-align: justify;"> </div>
<div style="text-align: justify;">
Other features remain the same like DSEE Extreme, Voice Assistant support,
quick attention, and ambient sound mode, Fast Pair for Android, and Swift Pair for
Windows also help with pairing. I am aware that there are some changes to the tap function but I suggest looking at reviews for that information.<br /></div>

We can see the new driver is bigger but also flatter, similar to what we
see in Sony's WH line of headsets. In the interview, the engineers say that
there are 2 methods for high sound pressure reproduction. First, using a
larger diaphragm to increase the vibration area, and second using a small
diaphragm to generate a larger vibration amplitude. Sony uses the former in the
new WF-1000XM5, where as the latter was used in the WF-1000XM4. <br />
</div>
<div style="text-align: justify;"> </div>
<div style="text-align: justify;">
The interview also reveals that the new driver diaphragm is composed of 2
different materials, the central dome is more rigid, helping recreate higher
frequencies which are clearer and higher; where as the outer edge is softer
and more flexible which helps reproduce deep low frequencies. This design is
similar to the WH-1000XM5 diaphragm.<br />
</div>
<p style="text-align: left;">
We do have a close up of the driver from the WF-1000XM5 product page. I
suspect this is the idealized rendered version, but it does provide a nice
close up of the design.<br />

The driver in the WF-1000XM5 takes up a lot more space in the earbuds, which
themselves are smaller than the WF-1000XM4, where the driver seems much
smaller with respect to the other components. I am looking forward to
comparing both devices in the future together.<br />
</p>
<p style="text-align: justify;">
Also one more thing, in the product video, there is an exploded view and we
can see a piece of plastic that is some kind of cover that goes over the main outlet of the earbuds.<br /></p>
<div class="separator" style="clear: both; text-align: center;">

<p style="text-align: justify;">
It covers the entire bottom of the earbuds, perhaps creating a seal with the
outside, maybe for the IPX4 certification. Silly question, would this plastic
piece not dampen the sound coming from the driver? I am also wondering if it
is glued in or just pushed into place. <br />
</p>
<p style="text-align: left;"><b>Noise Cancellation</b></p>
<p style="text-align: justify;">
One the major selling points of the WF-1000XM5 will be the noise cancellation.
Sony claims they are the best noise cancelling headset on the market right
now. (July 2023) Because the new driver is able to produce more sound pressure, it is able
to produce more accurate cancellation waves in the lower frequencies to cancel
out noise.
</p>
<p style="text-align: left;">
The new model now features 3 NC mics per earbud. When I first saw the product
video, I was puzzled why there was a microphone in the middle of the earbuds
with no hole.
</p>

</div>
<p style="text-align: left;"></p>
<p style="text-align: left;">
Reading the press released explained the reason:
</p>
<div style="text-align: justify;">
<blockquote>
The WF-1000XM5 now feature three microphones on each earbud, including dual
feedback mics, which improve low-frequency cancellation performance. This is
Sony’s biggest ever step forward in noise cancelling, resulting in ambient
sound captured even more accurately.
</blockquote>
</div>
<div style="text-align: justify;"> </div>
<div style="text-align: justify;">
This is also expanded upon in the
<a href="https://www.sony.jp/feature/products/headphone/230726_01/?s_pid=jp_/headphone/_products_WF-1000XM5" target="_blank">Engineer interview,</a>
the extra feedback microphone in the middle of headset helps with cancelling
the lower frequency range. In addition, the microphones are newly developed,
smaller in size and have less noise. Although I am uncertain if this is
referring to all 3 NC mics, or just the additional feedback one. For
comparison, Apple decided to increase the size of the microphones in their new
Beats Studio Buds +, but I cannot find any teardown photos of the new model to
compare the mic size with the older model.<br />
</div>
<div style="text-align: justify;">
<br />
<div style="text-align: justify;">
From my understanding, Sony uses the same mic for voice and feedforward NC
in the WF-1000XM5, like in the LinkBuds S. It is an interesting decision, I
suppose if it works in the LinkBuds S, it would work here as well. The
absence of a dedicated voice mic does not bother me, but if the call quality
is not improved over the WF-1000XM4, then I could see this being an issue
for users who use the voice mic a lot. Sony has <a href="https://thewalkmanblog.blogspot.com/2023/07/sony-wf-1000xm5-firmware-update-version-2-0-1.html" target="_blank">released a firmware update</a> to address the rather mediocre voice call quality.<br /></div>
<div style="text-align: justify;"><br /></div>
<div style="text-align: justify;">
Could Sony have fit in a 4th microphone for voice? Good question, perhaps,
but maybe the benefits of a 4th microphone outweighed the costs.<br />

<div style="text-align: justify;">
The two feedback NC microphones are positioned in 2 different areas, the
first microphone is inside the audio canal, with the second microphone
closer to the driver. The placement of the NC microphone in the audio canal
is why the eartips now require a mesh, since none exists on the actual
unit.<br />

</div><div style="text-align: justify;">Going back to the earlier part where there is a plastic cover over the outlet, I wonder how the flex PCB with this microphone goes out, maybe there is a notch in the plastic cover? Or perhaps the flex PCB just fits between the cover and case? Hopefully this can be revealed in a teardown.</div><div style="text-align: justify;"> </div><div style="text-align: justify;">The noise cancellation is improved according to Sony, who have a graph on the Japanese product page. According to the graph, there are improvements in the low to mid frequency ranges. The new model looks to also improve the cancellation of human voices, which is an area NC struggles.<br /></div><div style="text-align: justify;"></div><div style="text-align: justify;"></div><div style="text-align: justify;"><br />

But this is just technical information with real world performance probably varying.</div><div style="text-align: justify;"><br /></div><div style="text-align: justify;">Personally I am looking forward to see the review and comparison from <a href="https://www.youtube.com/@ThisIsTechToday" target="_blank">This is Tech Today</a>.

We first learned of the 2 processors from the leaks, but now we have a bit
more information why the extra processor was required. Because Sony added a
second feedback NC microphone inside, additional processing power was
required. This is where the QN2e comes in.
</div>
<div style="text-align: justify;"> </div>
<div style="text-align: justify;">
We have little information about the QN2e, it could be a new chip, or an
evolution of the QN1e, whatever the case I suspect it will be close to the
QN1e's design as seen below.<br />

<div style="text-align: justify;">
Sony does have a CXD3782 chip which has 3 microphone inputs, but it uses a lot more power, 13mW, versus only 7mW for
the CXD3871. We will probably have to wait for a teardown to identify the
chip. Perhaps the FCC filing will reveal the chips under the metal cover,
just like we saw in the LinkBuds S, but if not, maybe 52Audio will perform a
teardown and remove the lid to reveal the chips. If that does not happen, I could always try to fund raise for a teardown and take one apart myself if people would want me to.<br />
</div>
<div style="text-align: justify;"> </div>
<div style="text-align: justify;">
Moving to the V2 integrated processor, the engineer interview reveals that
the SoC is a new chip, but provides no specifics. I have already identified
the chip as the Mediatek MT2833 in an
<a href="https://thewalkmanblog.blogspot.com/2023/07/where-is-sony-wf-1000xm5.html" target="_blank">earlier post</a>. We also have little information on this chip, but from Google's
<a href="https://developers.google.com/nearby/fast-pair/chipsets" target="_blank">Fast Pair compatibility list</a>, we can see that this chip is paired with the AB158x. Long ago on a
Mediatek employee's LinkedIn page, they had the MT2833 paired with the
AB1588, so I am going to assume this is the case.<br />
</div>
<div style="text-align: justify;"> </div>
<div style="text-align: justify;">
I cannot find much on the AB1588, but there is an
<a href="https://www.airoha.com/products/p/UATZlIz8hZq3TDky" target="_blank">AB1585 on the Airoha website</a>. But from other Airoha products and their documentation, I am
certain that the AB1588 is the same as the AB1565, but with more embedded
flash. I found this
<a href="https://www.wpgdadatong.com/solution/detail/70456" target="_blank">ANC diagram of the AB1565</a>, and looking at the inputs, we have the 2 NC mics and a voice mic.

<div style="text-align: justify;"> </div><div style="text-align: justify;">I would not expect the AB1588 to have any more additional inputs, meaning the
extra feedback NC microphone could not be processed by the SoC. So I am
wondering myself now how Sony has setup the connections in the WF-1000XM5. Is
the QN2e only processing the one extra NC mic, or all 3? And what about the
MT2833 (V2)? Does it still play a role in any noise cancellation? I do not
think we will ever get an exact answer to that question, but in the engineer
interview, it is mentioned that the V2 works in conjunction with the QN2e to cancel out noise.
</div>
<div style="text-align: justify;"><br /></div>
<div style="text-align: justify;">
I will have another new post in the future about the V2 and the various other
Sony and Airoha SoCs. So stay tuned.

I am hopeful the FCC internal photos will become available sooner than August 22nd, but for the
time being we have one photo from the Engineers interview, which I have
supplemented with additional photos from the March 2023 leak.

I still cannot identify the small (#9) chip, maybe it is related to charging
as this is where the charging pins are located. While we do not have photos of the

Thanks for reading and sorry it took so long, most of the other sites got the information ahead of time and could prepare, I could not.<br /></p><p style="text-align: center;"><iframe frameborder="0" marginheight="0" marginwidth="0" sandbox="allow-popups allow-scripts allow-modals allow-forms allow-same-origin" scrolling="no" src="//ws-eu.amazon-adsystem.com/widgets/q?ServiceVersion=20070822&OneJS=1&Operation=GetAdHtml&MarketPlace=DE&source=ss&ref=as_ss_li_til&ad_type=product_link&tracking_id=walkmanblog04-21&language=en_GB&marketplace=amazon&region=DE&placement=B0C4TLFZSZ&asins=B0C4TLFZSZ&linkId=d0b6b6af7ffe79b20f815978a8fbe79c&show_border=true&link_opens_in_new_window=true" style="height: 240px; width: 120px;"></iframe> <iframe frameborder="0" marginheight="0" marginwidth="0" sandbox="allow-popups allow-scripts allow-modals allow-forms allow-same-origin" scrolling="no" src="//ws-eu.amazon-adsystem.com/widgets/q?ServiceVersion=20070822&OneJS=1&Operation=GetAdHtml&MarketPlace=DE&source=ss&ref=as_ss_li_til&ad_type=product_link&tracking_id=walkmanblog04-21&language=en_GB&marketplace=amazon&region=DE&placement=B0C4TJXPNJ&asins=B0C4TJXPNJ&linkId=87376755127c3dd7d0fa16d91c643ced&show_border=true&link_opens_in_new_window=true" style="height: 240px; width: 120px;"></iframe> <iframe frameborder="0" marginheight="0" marginwidth="0" sandbox="allow-popups allow-scripts allow-modals allow-forms allow-same-origin" scrolling="no" src="//rcm-na.amazon-adsystem.com/e/cm?lt1=_blank&bc1=000000&IS2=1&bg1=FFFFFF&fc1=000000&lc1=0000FF&t=ws-e-20&language=en_CA&o=15&p=8&l=as4&m=amazon&f=ifr&ref=as_ss_li_til&asins=B0C33XXS56&linkId=34c8775f114f21e36a976915601854e6" style="height: 240px; width: 120px;"></iframe> <iframe frameborder="0" marginheight="0" marginwidth="0" sandbox="allow-popups allow-scripts allow-modals allow-forms allow-same-origin" scrolling="no" src="//rcm-na.amazon-adsystem.com/e/cm?lt1=_blank&bc1=000000&IS2=1&bg1=FFFFFF&fc1=000000&lc1=0000FF&t=ws-e-20&language=en_CA&o=15&p=8&l=as4&m=amazon&f=ifr&ref=as_ss_li_til&asins=B0C345M3T7&linkId=3337ce37b4ea1bb2fc699940bde4c74e" style="height: 240px; width: 120px;"></iframe><br /></p>Ascarisshttp://www.blogger.com/profile/09919961371892892332noreply@blogger.com29tag:blogger.com,1999:blog-2953732317018979267.post-1222577475701348152023-07-25T20:37:00.005-07:002023-07-25T20:37:34.836-07:00Sony WH-1000XM5 Firmware update version 2.0.2<div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEixsZYwcSPUAcy6QpgPmkBXKxdnh-3GlLmENhk5ZryNKmNxBM0hUXh8_L2YNeGrOC-QwH-tcYhqmuSOBovH9ZNFInmNN036hFqQOZOYxqq1-GWnaYZJOANKPz9p_dGXHBG2-0lIgOGA4fTOxtMAYY5ZFKCQp_g25tKVwhlyhsZhwX0bgvPxD2yDE_6D0WWv/s1200/wh1000xm5_fw_2-0-0.jpg" style="margin-left: 1em; margin-right: 1em;"><img alt="Sony WH-1000XM5 Firmware update version 2.0.2" border="0" data-original-height="729" data-original-width="1200" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEixsZYwcSPUAcy6QpgPmkBXKxdnh-3GlLmENhk5ZryNKmNxBM0hUXh8_L2YNeGrOC-QwH-tcYhqmuSOBovH9ZNFInmNN036hFqQOZOYxqq1-GWnaYZJOANKPz9p_dGXHBG2-0lIgOGA4fTOxtMAYY5ZFKCQp_g25tKVwhlyhsZhwX0bgvPxD2yDE_6D0WWv/s16000/wh1000xm5_fw_2-0-0.jpg" title="Sony WH-1000XM5 Firmware update version 2.0.2" /></a></div><p></p><p style="text-align: justify;">The WH-1000XM5 firmware has been updated to version 2.0.0. The update finally brings LDAC support during multipoint use. Here are all the changes in this update:<span></span><br /></p><span><a name='more'></a></span><ul style="text-align: left;"><li>Makes LDAC available during a multipoint connection</li><li>Apps that can be linked have been added</li><li>Adds support for Head Tracking</li></ul><p style="text-align: justify;">The head tracking might bring gesture support like the WF-1000XM5 but this is just a guess. The LDAC multipoint support is a big deal as many users have been asking for this.</p><p style="text-align: justify;">I am not sure I will be updating just yet, I do use the multipoint, or need head tracking. I do not even use any linked apps. Will see what users post on reddit before making a final decision.</p><p style="text-align: justify;">As with all updates, make sure your headset and phone are fully charged before updating.</p><p style="text-align: center;"><iframe frameborder="0" marginheight="0" marginwidth="0" sandbox="allow-popups allow-scripts allow-modals allow-forms allow-same-origin" scrolling="no" src="//ws-na.amazon-adsystem.com/widgets/q?ServiceVersion=20070822&OneJS=1&Operation=GetAdHtml&MarketPlace=US&source=ss&ref=as_ss_li_til&ad_type=product_link&tracking_id=thew017-20&marketplace=amazon&region=US&placement=B09XS7JWHH&asins=B09XS7JWHH&linkId=7364fa221c5c486dbfa531eb0d0469bf&show_border=true&link_opens_in_new_window=true" style="height: 240px; width: 120px;"></iframe> <iframe frameborder="0" marginheight="0" marginwidth="0" sandbox="allow-popups allow-scripts allow-modals allow-forms allow-same-origin" scrolling="no" src="//ws-na.amazon-adsystem.com/widgets/q?ServiceVersion=20070822&OneJS=1&Operation=GetAdHtml&MarketPlace=US&source=ss&ref=as_ss_li_til&ad_type=product_link&tracking_id=thew017-20&marketplace=amazon&region=US&placement=B0BXYCS74H&asins=B0BXYCS74H&linkId=80f7837bcafd27d771209f4d17982fe8&show_border=true&link_opens_in_new_window=true" style="height: 240px; width: 120px;"></iframe> <iframe frameborder="0" marginheight="0" marginwidth="0" sandbox="allow-popups allow-scripts allow-modals allow-forms allow-same-origin" scrolling="no" src="//ws-na.amazon-adsystem.com/widgets/q?ServiceVersion=20070822&OneJS=1&Operation=GetAdHtml&MarketPlace=US&source=ss&ref=as_ss_li_til&ad_type=product_link&tracking_id=thew017-20&marketplace=amazon&region=US&placement=B0BXYCS74H&asins=B0BXYCS74H&linkId=80f7837bcafd27d771209f4d17982fe8&show_border=true&link_opens_in_new_window=true" style="height: 240px; width: 120px;"></iframe><br /></p><p></p>Ascarisshttp://www.blogger.com/profile/09919961371892892332noreply@blogger.com4tag:blogger.com,1999:blog-2953732317018979267.post-16714485548755144902023-07-25T20:24:00.005-07:002023-07-25T20:39:16.320-07:00Sony WF-C700N Firmware Update, version 2.0.0<div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgQx4rdUV0sFbuQAfvnIVcpFnPkNOidSQjjExfwr6C_GHr8ZVoQ16i7_Q5u5Pzk1F3rEbxfxi9okGJZSMMsgcWtG56vIES3yjlfoEOrfJmiMCQAHvyE0Msp1ge5yrVVTZ5_86mk7xqIdvDywHBxN6ZMfKvnCEI-M2LncgYwkeXcrrPPA1M0Y7VxYh5zGyjn/s1080/wf-c700n_fw_2-0-0.jpg" style="margin-left: 1em; margin-right: 1em;"><img alt="Sony WF-C700N Firmware Update, version 2.0.0" border="0" data-original-height="640" data-original-width="1080" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgQx4rdUV0sFbuQAfvnIVcpFnPkNOidSQjjExfwr6C_GHr8ZVoQ16i7_Q5u5Pzk1F3rEbxfxi9okGJZSMMsgcWtG56vIES3yjlfoEOrfJmiMCQAHvyE0Msp1ge5yrVVTZ5_86mk7xqIdvDywHBxN6ZMfKvnCEI-M2LncgYwkeXcrrPPA1M0Y7VxYh5zGyjn/s16000/wf-c700n_fw_2-0-0.jpg" title="Sony WF-C700N Firmware Update, version 2.0.0" /></a></div><p></p><p style="text-align: justify;">The WF-C700N multipoint firmware is finally here, Sony said Summer 2023, and it looks like they got out pretty quickly. I will be updating my headset later today once it is charged up to test it out. Here are the changes:<span></span></p><a name='more'></a><p></p><ul style="text-align: left;"><li>Adds the ability to simultaneously connect to 2 devices</li><li>Adds a method to adjust the volume while playing music</li><li>Improves other functions</li></ul><p style="text-align: justify;">I am wondering about the second point regarding the volume. I have no issues with adjusting the volume when I use the left earbud, but it does not work on the right one when I use it by itself. Maybe this addresses that issue.<br /></p><p style="text-align: justify;">I am also curious about the "improves other functions" point, what else changed? Other is a very loose term.</p><p style="text-align: justify;">As with all updates, make sure your phone and headset are fully charged before starting the update.</p><p style="text-align: center;"><iframe frameborder="0" marginheight="0" marginwidth="0" sandbox="allow-popups allow-scripts allow-modals allow-forms allow-same-origin" scrolling="no" src="//ws-na.amazon-adsystem.com/widgets/q?ServiceVersion=20070822&OneJS=1&Operation=GetAdHtml&MarketPlace=US&source=ss&ref=as_ss_li_til&ad_type=product_link&tracking_id=thew017-20&marketplace=amazon&region=US&placement=B0BYPFNW6T&asins=B0BYPFNW6T&linkId=942ae47dc5268fecacd748e94736e9c1&show_border=true&link_opens_in_new_window=true" style="height: 240px; width: 120px;"></iframe> <iframe frameborder="0" marginheight="0" marginwidth="0" sandbox="allow-popups allow-scripts allow-modals allow-forms allow-same-origin" scrolling="no" src="//ws-na.amazon-adsystem.com/widgets/q?ServiceVersion=20070822&OneJS=1&Operation=GetAdHtml&MarketPlace=US&source=ss&ref=as_ss_li_til&ad_type=product_link&tracking_id=thew017-20&marketplace=amazon&region=US&placement=B0BYPGGDZX&asins=B0BYPGGDZX&linkId=f7a4f1d72e881e417603bc939b4c9005&show_border=true&link_opens_in_new_window=true" style="height: 240px; width: 120px;"></iframe> <iframe frameborder="0" marginheight="0" marginwidth="0" sandbox="allow-popups allow-scripts allow-modals allow-forms allow-same-origin" scrolling="no" src="//ws-na.amazon-adsystem.com/widgets/q?ServiceVersion=20070822&OneJS=1&Operation=GetAdHtml&MarketPlace=US&source=ss&ref=as_ss_li_til&ad_type=product_link&tracking_id=thew017-20&marketplace=amazon&region=US&placement=B0BZQM5ZDL&asins=B0BZQM5ZDL&linkId=5fbfb79559bc0d5d3aa4b852390229bc&show_border=true&link_opens_in_new_window=true" style="height: 240px; width: 120px;"></iframe><br /></p><p></p>Ascarisshttp://www.blogger.com/profile/09919961371892892332noreply@blogger.com0
