1. Replace the ear tips with ones that fit more snugly and ensure the earbuds are positioned correctly to create a tight seal. Improper fit can affect call quality.

2. Fully charge your earbuds and reset them by following these steps:

- Place the earbuds into the charging case and leave the case open.

- Press and hold the touch bar on the charging case for 5 seconds. A function menu will appear on the case's display. Slide to select Reset, then double-tap to confirm. After the reset is completed, a "Reset Successful" prompt will appear along with a single-tone chime, which will fade after 2 seconds. This confirms a successful reset.

Note: Ensure the earbuds are properly placed in the charging case and that the battery level is displayed on the charging case's screen for a successful reset.

3. Verify that "soundcore Liberty 4 Pro" is selected as the audio output device 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.
