Sony WF-1000XM6 iFixit Teardown

The internal battery is held in place with glue/tape, and is connected to the flex PCB using 2 contacts which can be seen below. Previously both the WF-1000XM3 and WF-1000XM4 used similar contacts, with Sony deciding to switch things up with the WF-1000XM5, and soldering the battery to the flex PCB. The return to physical contacts and no soldering is encouraging.

After removing the battery, we can see the first feedback MEMS microphone, and the connections for the charging contact pins (yellow arrows).

This is where iFixit stopped the earbud teardown as they did not want to damage the rest of components, while attempting to remove them. Makes sense.

Thanks to Lumafield, who provided the amazing CT scans in the video, we get to see that there are 2 chips inside the SiP under the resin as suggested by the video from Sony.

The Sony product video is not entirely 100% representative of the actual layout on the PCB, but it does show that the QN3e is larger than the V2, matching the photo from the Lumafield scan.

It is unfortunate that the chips were not revealed in the FCC filing.

Moving to the charging case. To open up the case, insert a plastic pick between the top of the inside and the edge. Run the pick around the perimeter of the edge to unclip the top from the bottom. There should be 8 clips, 2 on each side.

Be careful not to apply too much pressure on the edge of the bottom section, as it can break.
