Troubleshooting
If you encounter issues with your headset, please refer to the following common solutions:
- Headset not powering on:
Ensure the headset is fully charged. Connect it to the charging cable and allow it to charge for at least 30 minutes before attempting to power on again. - Cannot pair with device:
Make sure the headset is in pairing mode (LED flashing blue and red). Ensure Bluetooth is enabled on your device and that the headset is within the 10-meter Bluetooth range. Try turning Bluetooth off and on again on your device. If issues persist, restart both the headset and your device. - No sound or low volume:
Check the volume levels on both the headset and your connected device. Ensure the headset is properly connected to your device. If using multipoint, ensure the correct device is actively playing audio. - Poor call quality (microphone issues):
Ensure the microphone boom is positioned correctly near your mouth. Check for any obstructions. Verify that the microphone is not muted. Background noise can be reduced by the AI noise-cancelling feature, but extreme noise may still affect clarity. - Intermittent connection:
Ensure there are no physical obstructions between the headset and your device. Move closer to your device to ensure you are within the 10-meter Bluetooth range. Avoid environments with strong Wi-Fi or other wireless interference.
