Initializing the headset to restore factory settings
If the headset does not operate correctly even after resetting, initialize the headset.
Turn off the headset while the USB Type-C cable is disconnected and then press and hold the 
(power) button and the C (custom) button simultaneously for 7 seconds or more.
The indicator (blue) flashes 4 times (
), and the headset is initialized. This operation resets volume settings, etc. to the factory settings, 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
- If you have updated the software after purchasing the headset, even if you initialize the headset, the software is retained updated.
- When you initialize the headset to restore the factory settings after you change the language of the voice guidance, the language will also return to the factory setting.
- After the indicator (blue) flashes 4 times and the headset is initialized, it may take about 1 minute to accept the
(power) button operation again.
