What to do if one earbud has no sound when using the Xiaomi OpenWear Stereo Pro?

If one earbud has no sound when using the Xiaomi OpenWear Stereo Pro, please refer to the following information:
1. One earbud may have a low battery or poor contact with the ear or earhook, which can cause no sound. It is recommended to ensure both earbuds are sufficiently charged and properly positioned in your ears.
2. Dirt or debris can block the earbud speaker, affecting sound output. Gently clean the earbud openings with a soft brush or cotton swab to remove dust, earwax, or other particles.
3. Delete the earbuds from your device’s Bluetooth list and pair them again.
4. Outdated firmware or app versions can cause audio issues. Please update both the earbuds’ firmware and the Xiaomi Earbuds App to the latest versions.
5. If there is no sound, try connecting to another phone and testing again, or test with a different audio source.
6. Reset the device, restart the phone, then connect it to see if there is a sound.
If the above troubleshooting steps fail, the issue may be due to a hardware failure. We request that you visit our local after-sales center for further assistance.
