    • Since the Technics Headphone enclosure was glued together, the only way in was to cut into the headphone. The glue was light and the Touch Sensor cap came away with only a little force applied around headphone at the Touch Sensor cap seam

    • Since the headphone was easy to open to access its components, it may be possible to perform battery changes without damaging the headphone. This is the first possible self serviceable headphone that I have performed a teardown on

    • A utility knife was used at the Touch Sensor cap seam to help loosen and pry the Touch Sensor cap loose. When the Touch Sensor cap appeared loose, a Jimmy Tool was used to pry the cap free to open the headphone

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

    • Battery

    • Speaker Chamber

    • Bluetooth Radio/MCU and Antenna

    • MEMS Microphone

    • Opening up the headphone, we can see the main PCB, Antenna, and Battery

    • Battery is Li-ion 3.7V / 0.32Wh or 3.7V / 86mAh. The battery appears to be from VDL Electronics Co., Shenzhen, China

    • MEMS Microphones for Voice Call and Surrounding Sound

    • Antenna

    • Double Side Foam Tape

    • With the battery moved out the way, we can see the USB and Charging Interface connections, and Speaker Chamber

    • USB and Charging Interface Connectons - well marked and with test points

    • Speaker Chamber

    • Peeling back the Antenna from the double sick tape revealed the Main PCB, and that the Main PCB is held in place with a Phillips Head #00 Screw that was also marked on the PCB

    • Once the Phillips Head screw was removed, a small plastic collar had to be removed using tweezers to access the touch sensor PCB

    • With the Main PCB moved out the away, the touch sensor was pried out using a pry tool.

    • Care must to be taken with this step as it is easy to crack the Touch Sensor PCB while prying it out

    • Double sided foam tape was used to hold the touch sensor in place

    • Turning our attention back to the Battery side of the Headphone and moving the battery out of the way, we see that the USB and Charging Interface PCB is also held in place with a Phillips Head #00 Screw

    • Removing the screw, and gently prying against the Charging and USB Interface PCB allowed it to come free and be removed from the Headphone Enclosure

    • The USB and Charging / Interface PCB was held in place via double sided foam tape

    • While removing the USB and Charging Interface PCB, a small circular disk was found covering the larger connection hole on the enclosure. This disk is magnetic may be used to help hold the headphone in the charger. The disk was also held in place with foam tape

    • Now, on to removing the Speaker Chamber. The Speaker Chamber has a backside MEMS Microphone used for Noise Cancelation and Speaker Sound detection

    • Another nice find here, was that the Speaker Chamber MEMS Microphone flex PCB was connected to the Main PCB via a low force latching connector. Lifting the connector latch allowed the MEMS Microphone PCB to come free

    • This flex PCB also host the Battery wire solder connections for the system

Any suggestions on how to clean ear wax out of the small microphone port hole located just below the printed L/R letters on the inner face of the earbuds?

I used a single plastic bristle pulled from a small electric razor head cleaning brush, held by a tweezer, and rotated in the hole to loosen debris and kind of kinked the bristle and dragged laterally to flick/pull and debris out of the channel and that seemed to work.

I was reassured based on this teardown that stated the port was fabric and mesh protected on the inside such that I couldn't damage the mic this way, but if there is a better way to do this, i'd like a suggestion

Thanks for the teardown!
