7. Troubleshooting
If you encounter any issues with your H66 Earbuds, please refer to the following common solutions:
Earbuds Not Connecting/Pairing
- First-time Use: For the very first time, ensure the earbuds are in pairing mode. Take them out of the case, and press the multifunctional button (touch sensor) constantly for about 5-10 seconds until you see red and blue lights flashing or hear a "pairing" sound. Then search for them on your device.
- Bluetooth On: Ensure Bluetooth is enabled on your device.
- Device Range: Make sure the earbuds are within the operating range (10-20 meters) of your device.
- Reboot: Place the earbuds back into the charging case, close the lid, wait a few seconds, then take them out again to reset the connection.
- Forget Device: On your device, go to Bluetooth settings, forget or unpair "H66", then try the pairing process again.
- Charge Level: Ensure both earbuds and the charging case have sufficient battery.
Only One Earbud Working
- Charge Both: Ensure both earbuds are charged.
- Reset: Place both earbuds back into the charging case, close the lid, and then take them out simultaneously. They should automatically connect to each other.
- Re-pair: If the issue persists, try forgetting the device on your phone and re-pairing both earbuds from scratch.
Sound Quality Issues
- Ear Tip Fit: Ensure you are using the correct size ear tips for a snug fit to optimize sound quality and passive noise isolation.
