Introduction

The Bluetooth Transceiver, also called the NFC chip is a small green chip that manages bluetooth capabilities. It is located in the left ear cup and requires soldering and desoldering to replace.

  1. Start by inserting the iFixit plastic opening tool in the crease between the hard plastic and the ear cup, and then gently apply pressure until it separates. You may need to repeat the process on back until it is completely separate. This may take a considerable amount of pressure, but do not force it.

    • Unlike the right ear cup, there is no ribbon cable directly connecting the rest of the headphones to the outer cup.

  4. Using the JIS #00 screwdriver, remove the two 6.4 mm screws holding the NFC chip in place over the motherboard. Once the screws are removed, gently turn over the board to the left to expose the soldered connection points.
