Why does the person on the other end of the call only hear a low and unclear voice?
We suggest trying the following:

- If you only use one earbud, make sure the other earbud is in the charging case.
- Try different sizes of ear tips that come with the earbuds and make sure you're wearing them in the correct position to create a tight seal.
- Please make sure the audio output device chosen is "Soundcore Sport X10" on the connected device.
- If you make a call via an app, please try using your phone to make a call and see if the problem still persists.
- Try testing your earbuds with a different Bluetooth device in a different environment to see if it makes any difference.

If you have additional questions, please contact us at
service@soundcore.com for further assistance. Make sure to mention that you have tried the steps in this FAQ so our agents do not ask you to repeat them.
