1. If using only one earbud, make sure the other earbud is in the charging case.
2. Try out different ear wings and check that they seat well and create a tight seal in your ears. If they are not worn correctly, call quality may be affected.
3. Ensure "soundcore Liberty buds" is selected as the audio output on your connected device and increase the volume on your device.
4. If the call was made through an app, try using your phone's native calling feature instead to see if the issue persists.
5. Test the earbuds with a different Bluetooth device and in a different environment to see if there is any difference.
