Resetting the headset
If the headset cannot be turned on, or if it cannot be operated even when it is turned on, connect the headset to a booted computer using the supplied micro-USB cable, then press the 
button and NC/AMBIENT button simultaneously. The headset will be reset. Pairing information is not deleted.
To charge the headset after resetting, disconnect and reconnect the micro-USB cable.
If the headset does not operate correctly even after resetting, initialize the headset to restore factory settings.
