Before using your headset for the first time, it is recommended to charge it with a Sony charger. The LED indicator turns green when the battery is fully charged.
A drained headset needs to charge for up to 2 hours to be fully charged. Battery life is approximately 7.5 hours while listening to music or approximately 9 hours while handling calls if the temperature is 25 °C (77 °F).
Your headset has a capless USB port. The USB port must be completely dry before a cable can be connected for charging.
To charge your headset
- Connect one end of the charging cable to the charger or the USB port of a computer.
- Connect the other end of the cable to the USB port on your headset.
