If you're experiencing poor call quality when using your soundcore AeroFit Pro earbuds, there are several tips and tricks you can use to enhance the call quality and improve your overall listening experience. In this article, we'll be sharing effective strategies for fixing low and unclear voice on calls when you use the soundcore AeroFit Pro earbuds. To fix this issue, please try the following steps;

1. Confirm whether the earbud speaker is blocked. If there is a blockage, please try to use a Q-tip with a bit of rubbing alcohol to gently clean it.

2. If you are only using one earbud, ensure that the other earbud is in the charging case.

3. Make sure you have raised both the volume of the earbuds and the connected device to the maximum.

4. Ensure that you are wearing the earbuds in the correct position. If the earbuds are not worn properly, you may not achieve the correct call performance.

5. Ensure that the audio output device selected is "soundcore AeroFit Pro" on the device.

6. If you make a call through an app, try using your phone to make a call instead to see if the problem persists.

7. Try testing your earbuds with a different Bluetooth device in a different environment to see if there is any difference.

8. Upgrade the soundcore app and firmware to the latest version.
