This article provides a comprehensive guide on how to significantly improve your call quality and ensure your voice is heard clearly on the other end. Let's dive into the solutions to enhance your calling experience with V20i earbuds.

1. What should I do if the call quality of the earbuds is poor?

• Make sure you have raised both the volume of the earbuds and the connected device to the maximum level.
• Make sure you're wearing the earbuds in the correct position.
• Try switching to the phone mic and making a call to see if the problem still persists.
• Upgrade the soundcore app and firmware to the latest version.
• Reset your earbuds:

1. Take the earbuds out of the charging case.

2. Tap and hold the touch-control area on both earbuds for 10 seconds. After 3 seconds, their lights will flash

rapidly and you'll hear a pairing notification sound.  Continue holding for about 6 more seconds

until another sound confirms the successful reset.

2. What should I do if my voice sounds low and unclear to the person on the other end of the call?

• 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 or a small, clean brush to gently clean it.
• If you are only using one earbud, ensure that the other earbud is in the charging case.
• Ensure that you are wearing the earbuds in the correct position. If the earbuds are not worn properly on your ears, you may not achieve the correct call performance.
• Ensure that the audio output device selected is "soundcore V20i" and turn up the volume on your device.
• If you make a call through an app, try using your phone to make a call instead to see if the problem persists.
• Try testing your earbuds with a different Bluetooth device in a different environment to see if there is any difference.
