Before beginning the repair, review the Sony WH-CH710N Not Charging troubleshooting page for possible solutions. If you have confirmed that the charging port is damaged, power off the headphones and disconnect them from the charger or audio cable before proceeding.

1. Adım 11 Sony WH-CH710N Charging Port
  Push on alternating sides of the JST connector, to release it.
  
  If that doesn't work, use a pair of tweezers to firmly grip the sides of the battery connector and pull straight away from the socket. Hold the tweezers closer to the connector to get a better grip.
  
  Avoid scratching the circuit board or damaging any wires in the process.
  
  If this step is not performed, the cord connected to the circuit board may still carry an electrical current, creating a risk of electric shock or damage to the board.
