7. Troubleshooting
If you encounter issues with your Langsdom TG12 earbuds, please refer to the following common solutions:
| Problem | Possible Solution |
|---|---|
| Earbuds not pairing | Ensure earbuds are charged. Place them back in the case, close, then open again to re-enter pairing mode. Forget the device on your phone's Bluetooth settings and try pairing again. |
| Only one earbud working | Place both earbuds back in the charging case, close the lid, wait a few seconds, then open the lid and take them out. This often re-syncs them. Check battery levels for both earbuds. |
| No sound or low volume | Check the volume on both your device and the earbuds. Ensure the earbuds are properly connected. Clean any debris from the earbud speaker mesh. |
| Charging case not charging | Try a different TYPE-C cable and power adapter. Ensure the charging port is clean and free of debris. |
| Poor call quality | Ensure the microphone is not obstructed. Move closer to your connected device. Environmental Noise Cancellation (ENC) helps, but extreme noise may still affect clarity. |
If the issue persists, please contact customer support.
