Since the Technics 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 Technics headphone along the seam in the headphone. Then a Jimmy Tool was used to open up the headphone. Tweezers and a Pick Tool were used to removed the electronics from the enclosure
Once opened, we get our first look at the inside of the headphone
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
