Troubleshooting
- Earbuds not pairing: Ensure both earbuds are out of the case and fully charged. Turn off and on your device's Bluetooth, then try pairing again. If issues persist, try resetting the earbuds (refer to specific reset instructions if available, or place them back in the case and try again).
- 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 re-syncs them.
- Charging issues: Check that the Type-C cable is securely connected to both the charging case and the power source. Ensure the charging contacts on the earbuds and inside the case are clean and free of debris.
- Low power reminder: The earbuds provide a voice reminder when the battery is low. Recharge them promptly to avoid interruption.
- Compatibility: These earbuds use Bluetooth 5.3 and are compatible with most Bluetooth-enabled devices, including Xiaomi phones.
