No sound, or people can't hear you
- Check the mute button or mute light on the device and in the app.
- In Teams, Zoom or your softphone, select this device as both microphone and speaker.
- For wireless models, make sure it's connected to the dongle or phone you think it is.
- Update the device firmware and the app.
Bluetooth or dongle won't pair
- Put the device in pairing mode and remove the old pairing from your phone or computer first.
- Plug the USB dongle directly into the computer, not a hub.
- Re-pair the dongle using the manufacturer's desktop app.
- Charge it fully: low battery can prevent pairing.
Keeps disconnecting or drops out
- Use the original cable or dongle and a direct port on the computer; long or cheap USB extensions cause dropouts.
- Turn off USB power saving on the computer (Windows: Device Manager → USB Root Hub → Power Management).
- Charge it: low battery causes Bluetooth dropouts.
- Update firmware and the meeting app.
Won't turn on or won't charge
- Charge it for at least 2–3 hours with the original cable.
- Try another USB port or charger.
- If the battery no longer holds a charge, contact the manufacturer about warranty service.
