6. Troubleshooting
If you encounter any issues with your S03 earphones, please refer to the following common solutions:
6.1 Pairing Issues / Only One Earbud Working
If your earbuds are not pairing together or only one earbud is working, a factory reset can often resolve the issue:

- Place in Case: Put both earbuds back into the charging case and close the lid.
- Reset: Open the charging case. Some models may have a small button inside the case to press and hold for 10-15 seconds until an indicator light flashes, signaling a reset. If no button, simply leaving them in the case for a few seconds and then taking them out can sometimes reset them.
- Re-pair: Remove both earbuds from the case. They should automatically try to pair with each other. Once they are paired with each other, re-enable Bluetooth on your device and search for "S03" to pair again.
6.2 No Sound or Low Volume
- Ensure the earphones are properly connected to your device.
- Check the volume levels on both your device and the earphones.
- Make sure the earphones are charged.
- Try restarting your device and re-pairing the earphones.
6.3 Charging Problems
- Verify that the charging cable is securely connected to both the case and the power adapter.
