Introduction

Steps 5 and 6 require de-soldering the connections on the circuit board and the earbud and soldering it in place.

Before beginning, make sure to discharge and power off the headphones completely.

Caution: soldering/desoldering presents potential for device damage and burns. Always solder/desolder in a well-ventilated area.

Step 5

  • Place the positive probe of the multimeter on the pin of the red circuit board connection.
  • Place the negative probe on the pin of the red connection on the earbud.
  • Measure the voltage across the pins. If the connections yield 0 V, desolder the pins.
  • Apply the last three steps for the orange connection to measure the voltage across the pins. Desolder the pins if the connection yield 0 V.
  • Soldering/desoldering presents potential for device damage and burns. Always solder/desolder in a well-ventilated area.
