6. Troubleshooting
Common Issues and Solutions
| Issue | Possible Cause | Solution |
|---|---|---|
| Headphones not pairing | Low battery, out of range, not in pairing mode. | Ensure headphones are charged. Place them back in the case and open the lid to re-enter pairing mode. Move closer to the device. |
| No sound or low volume | Device volume too low, headphones not connected, dirty drivers. | Increase device volume. Reconnect headphones. Clean the earbud grilles gently. |
| Sound leakage | Improper fit, very high volume. | Adjust the fit of the ear clips. Lower the volume. The Dipole Directional Sound Transmission Technology minimizes leakage, but extreme volumes can still cause some. |
| Poor call quality (mic) | Environmental noise, poor connection. | Ensure AI ENC is active. Move to a quieter environment. Check Bluetooth connection stability. |
| Battery drains quickly | High volume usage, frequent game mode use. | Reduce volume. Limit continuous use of game mode. Ensure headphones are properly seated in the charging case when not in use. |
If the issue persists, please refer to the official Moondrop support resources.
