What to do if there is no sound when using the REDMI Headphones Neo for music and calls?

If there is no sound when using the REDMI Headphones Neo for music and calls, please try the following steps to troubleshoot:
1. Check whether the headphones are fully charged. Make sure the headphones are sufficiently charged before use.
2. Increase both the media/call volume on the phone and the volume on the headphones to ensure the audio is not muted or set too low.
3. Disconnect Bluetooth, unpair the device from your phone’s Bluetooth settings, then restore the headphones to factory settings and pair them again.
4. Open the Xiaomi Earbuds App and reset the gestures and audio effects settings.
5. Try connecting the headphones to another phone or device for testing. If there is still no sound on other devices, please contact the after-sales service center for further assistance.
