You may just need to re-pair the headset to the USB dongle.
Follow the steps below to pair them together.
1. While the headset is powered off, hold down the power button until the headset status LED starts blinking red/green rapidly. The headset is now in pairing mode.

2. While the USB adapter is plugged in, use a small tool (e.g. paper clip, SIM tray ejector, etc.) to hold down the button inside the pinhole on the USB dongle until the dongle LED starts blinking rapidly. The USB dongle is now in pairing mode.

3. Bring the headset close to the dongle. Wait until both the headset LED and the USB dongle LED are solid. The headset and USB dongle are now paired together.
