If you are experiencing problems with soundcore V40i one earbud doesn't work or no sound, you can find a solution in this article.

1. Make sure the charging case has sufficient power. Place the earbuds into the charging case and charge for 1 hour. Take them out and try again.

2. Set the ear hook to the LV1 position and place the earbuds back in the case. The light bar should illuminate for 3 seconds and then turn off. If it doesn't, clean the charging contacts with a cotton swab dipped in alcohol, then try again.

3. If the issue persists, try resetting the earbuds:

Wear the earbuds and press and hold the touch-control area on both earbuds for 10 seconds. You'll hear a sound prompt and a beep when the reset is successful.

After the reset, the earbuds are disconnected from Bluetooth. To reconnect, toggle Bluetooth off and on on your device, then pair the earbuds again.
