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. Insert the earphones into the charging case

    2. charging_A8T_1

    After a few seconds, the indicators on the earphones and charging case will turn on.

    Click here if the indicators do not light up or start flashing ＞＞

  2. Press and hold the button on both sides of the earphones for about 15 seconds to initialize

    3. initializing_A8T

    After pressing and holding the button for 10 seconds, the indicator “flashes once”. Continue pressing for another 5 seconds until the indicator “flashes once” again.

    If you release your finger before the second time the indicator “flashes once”, initialization will not be complete.
    If you released your finger too early, perform the initialization process again from the start.

    Check that indicators on both earphones are turned off before performing the next operation.

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