Experiencing charging or connecting issues with one earbud can be frustrating. In this article, you will find some steps to resolve this issue:

I. One Earbud Fails to Charge or Connect

1. Stop charging and check if there is any moisture or sweat in the charging port of the charging case.

2. Clean the earbuds with a soft, dry cloth and the earbuds' charging contacts with a cotton swab lightly dipped in alcohol. Then, gently clean the speaker mesh with a small brush.

3. Use a clean cloth dampened with alcohol to gently clean the case's charging contacts. Once cleaning is complete, let the earbuds sit for two hours before charging them again.

4. Reset the earbuds: Return the earbuds to the charging case and leave the case open. Press the button on the case for more than 10 seconds. After 3 seconds, the case indicator light will start flashing white. After 10 seconds, the case indicator light will quickly flash white three times, indicating a successful reset.

II. One Earbud Has No Sound or Low Volume

1. Adjust the volume balance between the left and right earbuds in the soundcore app.

2. Reset the earbuds: Return them to the charging case and leave the case open. Press the case button for over 10 seconds. After 3 seconds, the indicator light will flash white. After 10 seconds, it will rapidly flash white three times, indicating a successful reset.

3. Use a Q-tip dipped in a small amount of rubbing alcohol or a small, clean brush to gently clean the metal mesh filter. If possible, try cleaning the filter with modeling clay to see if it works effectively. Finally, use a cotton swab or toothpick to remove the loosened particles.

4. Ensure the earbuds are worn at the correct angle.
