Sound is interrupted

sound_breaks

The following describes possible solutions when the sound is interrupted.
Try the methods below to see whether they help to resolve the problem.

Communication with the device may sometimes be unstable.

Changing the position or orientation of the device

If there is an obstructing object (our body, metal, wall, etc.) between the device and the earphones, use the device upon moving it to a position that allows for most stable communication, such as by inserting it into the rear pocket instead of the front pocket.

L earphone is the master and is used to connect with devices as well as the R earphone. Thus moving the device closer to the L earphone may help to improve the sound quality.

Also, orientation of the device may have a significant impact on communication.

Use the connected device in a position or orientation that allows for the most stable communication.

The battery level of the earphones might be running low.

Sound tends to be interrupted when the remaining battery level is low.
If there are frequent sound interruptions, charge the earphones.

Charging the earphones

  1. Charge the charging case

  2. charging_2_No-PC_charge_A7T + Charge 2 A7T

    5V TYPE

  3. Insert the earphones into the charging case

  4. charging_A7T_1
    charging_A7T_2

    The earphones power off and charging starts.

    During charging, the indicators on the earphones light up. Also, the indicator light on the charging case will turn on for a few seconds.

    When charging the earphones or charging case that have not been used for a long period of time, it might take some time for the indicators to light up. Wait for the indicators to light up.

Communication of the device may sometimes be unstable depending on the environment.

Using the earphones at a different location

Sound may be interrupted if the earphones are subject to radio interference at crowded areas or beside microwave ovens and other electronic equipment that emits radio waves.

Also, radio waves are transmitted and received both directly and via reflections from walls and other objects during Bluetooth® communication, so sound may also be interrupted even at places with good visibility and no obstructing objects.

This is a characteristic of Bluetooth® communication and is not a malfunction.

If there are frequent sound interruptions, use the earphones at a different location.

Restoring the earphones to the initial settings and re-establishing the connection may help to 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_A7T_1

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

    charging_A7T_2

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

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

  4. initialize_A7T

    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.

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