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

button and the -

button simultaneously for 7 seconds or more.

The indicator (blue) flashes 4 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.
