    • Since the Panasonic Headphone enclosure is glued together, the only way in was to cut into the headphone.

    • This is a destructive teardown

    • A Razsor Knife was use to cut into the Panasonic headphone along the seam in the headphone. Then a Jimmy Tool was used to open up the headphone

    • Once opened, we get our first look at the inside of the headphone

    • Opening up the headphone, we can see the main PCB, Battery, Speaker, etc. Tweezers and a Pick Tool were used to removed the electronics from the enclosure

    • Double sided foam tape was used to hold the main the PCB to the Battery and to the Touch Sensor / Antenna PCB. This foam tape had to be cut free. Then Denatured Alcohol was used to remove the foam tape glue from the PCBs and Battery

    • At first, I wasn't sure about the solder balls. Then I realized they are used to anchor the USB and Power Interface pins on the outside of the Headphone to the internal circuit board.

    • I had to used a soldering iron to remove the solder balls, so that the internal interface circuit board could be removed. I had to also remove solder from the speaker wires to free up the internal circuit board.

    • The internal circuit board was also attached a MEMS Microphone that appeared to be monitoring the Speaker Chamber of the Headphone, since it was faced in. I had to remove the outside panel with 'R' on it with a Razor Knife to free the MEMS Microphone. Once the MEMS Microphone was freed, the interface circuit board could be pulled out

    • Next the Speaker sound chamber cover was removed with the use of a Pick Tool and Tweezers. A Razor Knife was used to cut the glue holding the speak in place

    • The speaker had no identifiable markings

    • With Speaker removed, we can see the sound chamber and sound ports

If you can, can you post the teardown of the charging case too?

CChin - Antwort

Dong a web search, I believe the glue removed from the speaker was a silicone dome used to help compress sound waves?

Moe Moe's - Antwort

yes second the charging case!
