Device is not Charging

You are unable to recharge your headphones

Faulty Charging Cable

If you are unable to see the orange charging indicator when using the provided wire, try using a different wire with the same head. If the charging indicator (next to the power button) lights up green, then the issue is the cable.

Faulty Charging Port

If multiple charging wires do not work, giving no indication of charging, then the charging port may not be receiving power or be sending power to the battery. Check the port with a voltmeter to see if any resistance is registered. If there isn’t any, the port is faulty. See the following guide for replacement information. -

Battery Issue
