Resetting the headset
If the headset cannot be turned on or cannot be operated even when it is turned on, press the button and the NC/AMBIENT button simultaneously while charging. The headset will be reset. The device registration (pairing) information is not deleted.
To charge the headset after resetting, disconnect and reconnect the USB Type-C cable.
If the headset does not operate correctly even after resetting, initialize the headset to restore factory settings.
