Before using your headset for the first time, it is recommended to charge it with an official Sony charger. The LED indicator turns green when the battery level is above 85%, and goes off when your headset is fully charged.
A drained headset needs to charge for approximately 1.5 hours to be fully charged. Battery life while listening to music or handling calls is approximately 6 hours 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 the larger USB connector to the charger or the USB port of a computer.
- Connect the USB Type-C connector of the cable to your headset.
