The WF-H800 FCC teardown is also now available on their website, so let us take a look at what we can find out. The photos are not the best quality but it is the best we have for now. I will be comparing the parts to the WF-1000XM3 teardown by 52audio.com, so check out their site for the full teardown.
The first photo shows 2 main chips. While difficult to read, #1 is the Mediatek MT2811, while #2 appears to be the memory chip, Q128FWY, both are also present in the WF-1000XM3. A comparison of the chips on the WF-1000XM3 is below (via 52audio.com). As for #3, I believe this is the same as the 421E41R9, which according to 52audio is the battery protection chip.
On the reverse side of the WF-H800 is 1 more chip. This chip is under an RF shield that is seen in the the photo in the corner and the main photo is without the shield. The 3 pins on the right are the charging pins.
The chip under the RF shield is probably the Mediatek MT6388P which apparently is the power management chip like in the WF-1000XM3. See below.
The board on the WF-1000XM3 with the RF shield also has the charging pins which are remove in the above photo. Btw does anyone know what that metal part on the WF-1000XM3 is? Is it a heatsink?
The 2 main chips missing from the WF-H800 are the QN1e (D3781835) and the unknown 310819078266C chip that is on the same side as the QN1e. While not in the FCC filing, I would imagine the battery will be identical to the WF-1000XM3, the VARTA CP1254 Li-ion battery, 3.7V 0.2Wh. The battery can be seen in the photo below.
That is all the photos from the FCC teardown, so hopefully once the headset is released someone will do a complete teardown as well.
great teardown, it does look like its just a wf1000xm3 with no noise cancellation.
ReplyDeleteThat was my first thought when I saw the teardown photos on the FCC. If it we did not have the 52audio.com WF-1000XM3 teardown, it would be harder to say how it would compare and if similar components were used.
