Troubleshooting
- Earbuds not pairing with device: Ensure both earbuds are removed from the case and are powered on. Turn off and on your device's Bluetooth. Forget the device from your Bluetooth list and try pairing again. Ensure earbuds are charged.
- Only one earbud working: Place both earbuds back into the charging case, close the lid, wait a few seconds, then take them out again. This often resets the connection between the two earbuds. If the issue persists, try resetting the earbuds (refer to manufacturer's website for specific reset instructions if not covered here).
- No sound: Check the volume level on both your device and the earbuds. Ensure the earbuds are properly connected to your device. Try playing audio from a different application or source.
- Charging issues: Ensure the charging cable is securely connected to both the case and the power source. Check if the charging contacts on the earbuds and inside the case are clean and free of debris. Try a different charging cable or power adapter.
- Poor sound quality/intermittent connection: Ensure there are no obstructions between the earbuds and your device. Move closer to your device to reduce interference. Avoid using the earbuds in environments with strong electromagnetic interference.
