Sony WF-1000XM4 firmware update, version 1.1.5

Sony has released their first firmware update for the new WF-1000XM4. The version is now 1.1.5 and this update improves Bluetooth connection stability. Reading some reddit posts, it looks like some people have issues installing the firmware but I suspect this might be down to the earbuds powering down and the install failing.

Update instructions can be found here.

The most important thing is to keep the headphones turned ON and not have them turn off during the update. 

In the Sony | Headphones Connect app, set the Automatic Power Off function to Do not turn off. Once you have updated your headset, you can change this back to conserve battery when the headset is not in use. Make sure that both devices, phone/tablet and headset are fully charged.

If an update error message appears, press OK, insert the earbuds into the case and then take them out to restart them. Then restart the Sony | Headphones Connect app and try the update again.

With more and more people getting their hands on the new headset, more issues/bugs will show up and Sony will have more firmware updates. I would expect more improvements to connection stability and improvements as time passes.

As always post any update issues here or Reddit in the Sony subreddit or the headphones one.

     

Sony YY2951 shows up on Korean FCC (update 2)

Looks like Sony will have another wireless headset this year to complement the WF-1000XM4 and YY2952. Unknown what this is, could be a low end device, as it is made in Vietnam (see update).

Sony WF-1000XM4 now available on Amazon

The new WF-1000MX4s are available on Amazon. Certain regions have it out of stock, but Amazon says it is working on getting new stock. I do wonder how much stock Sony has shipped or provided to various retailers, most likely less than when the WF-1000XM3 shipped I would imagine.

After many leaks, Sony has finally announced the new WF-1000MX4. Most of the details leaked, so rather than post the press release and specs again, I will go over some of the new things for me.

Sony WF-1000XM4 shows up on second retailer

Another day, another retail listing. This will probably be removed shortly but I have gathered all the information from it. The listing provides two new details, the driver size, still 6mm unfortunately and that Speak-to-Chat uses Sony's Precise Voice Pickup technology which uses 4 microphones for better voice quality.
