- Make sure that the headset light control is turned on.
- Check whether the power supply of the headset is normal, and ensure that the headset can be turned on and off normally.
- Confirm the interface of the headset and the interface of the computer are no dirty. Please keep the interface clean to prevent poor contact.
- If the headsets have batteries, they should be charged in time to ensure that the batteries have enough power. If the battery power is too low, the headsets would work abnormally.
