Troubleshooting
| Problem | Solution |
|---|---|
| Headphones do not power on. | Ensure the headphones are fully charged. Connect to a power source and check the charging indicator. |
| Cannot pair with a device. | Ensure headphones are in pairing mode (LED flashing blue/red). Turn off and on Bluetooth on your device. Move headphones closer to the device. Clear previous Bluetooth connections on your device. |
| No sound or low volume. | Check volume levels on both headphones and the connected device. Ensure headphones are properly connected via Bluetooth. Try re-pairing the headphones. |
