Only the Left or Right Earbud Has Sound

Updated Jul 30, 2026

  1. 1. Place both earbuds in the charging case.
  2. 2. Make sure both earbuds are properly touching the charging contacts.
  3. 3. Leave the charging case lid open and press and hold the reset button on the back of the case for 5 seconds, until the indicator light changes from orange to green.
  4. 4. Clean the metal charging contacts on both the earbuds and the charging case.
  5. 5. Charge the earbuds and charging case for at least 10 minutes.
  6. 6. Delete the existing pairing record from your phone’s Bluetooth settings.
  7. 7. Remove both earbuds from the charging case at the same time and pair them again.

Do not connect the left and right earbuds separately. Your phone should connect to only one device named “Kinglucky Earbuds.”
