No sound from one side of the earphones


If no sound is heard from one side of the earphones, restoring the settings of the earphones to the initial state may solve the problem.
Follow the steps below to check whether there is any abnormality with the sound output.

Restoring settings to the initial state

  1. Press and hold the button on both sides of the earphones for about 3 seconds to turn off the power

  2. PLAY_button_LR_A10T

    The indicators on the earphones light up in red, and the power of the earphones turns off after the red light goes off.

  3. Press and hold the button on both sides of the earphones for about 20 seconds to initialize

  4. PLAY_button_LR_A10T

    The indicators will flash in white for three times every 10 seconds.

    If you release your finger before the second time the indicator flashes three times in white, initialization will not be complete.
    If you released your finger too early, perform the initialization process again from the start.

  5. Delete the registration information of the earphones from the BLUETOOTH® settings
