Initializing the headset to restore factory settings
Turn off the headset while the USB Type-C cable is disconnected and then press and hold the 
button and the NC/AMBIENT button simultaneously for 7 seconds or more.
The blue indicator flashes four times (
), and the headset is initialized. This operation resets volume settings, etc., and deletes all pairing information. In this case, delete the pairing information for the headset from the device and then pair them again.
If the headset does not operate correctly even after initializing, consult your nearest Sony dealer.
Note
- Even if you initialize the headset, the updated software is retained.
- Even if you initialize the headset after changing the language of voice guidance, the language will not be changed.
