Try a manual pairing of the headset and the dongle.
Hold the power button in the "On" position for 5 seconds on the headset, and then hold the button on the dongle for 5 seconds. This should force a manual pairing, allowing the PC to again recognize the headset.
Be sure to check multiple USB ports (to confirm it’s not an issue with the USB port).
If the dongle can’t be manually paired either, please contact customer support.
