Troubleshooting
If you encounter any issues with your Ltinist BX29 earbuds, please refer to the following common solutions:
- Earbuds not pairing: Ensure both earbuds are charged. Place them back in the case, close it, then open it again to re-initiate pairing mode. On your device, forget the "BX29" Bluetooth connection and try pairing again.
- Only one earbud working: Ensure both earbuds are charged. Try placing both earbuds back into the charging case, closing the lid, and then opening it again. This often resets the connection between the two earbuds.
- No sound or low volume: Check the volume level on both your device and the earbuds. Ensure the earbuds are properly seated in your ears and that the ear tips provide a good seal.
- Charging issues: Ensure the USB-C cable is securely connected to both the charging case and the power source. Check if the charging port is clean and free of debris.
- Unstable connection: Ensure your device is within the 50-foot Bluetooth range. Avoid obstacles between your device and the earbuds that might interfere with the signal.
If the issue persists, please contact customer support for further assistance.
