When the headphones are connected to a computer there is no sound or the microphone does not work

How to switch a computer's speaker or microphone settings to use the headphones ones.

    If you have successfully connected the headphones to a computer via Bluetooth but cannot hear sounds or the microphone does not work, you may need to change the computer settings:

    Note: The following shows the procedure for Windows 11. The menu items displayed on the computer may vary depending on the model or OS version.

    When no sound is heard from the connected headphones

    1. Open the Start menu and select Settings.
    2. Select System.
    3. Select Sound.
    4. Scroll down to the Advanced menu and select More sound settings.
    5. In the Playback tab, select Headphones, and click Set as Default Device.
    6. Select OK to close the setting screen.

    When the microphone on the connected headphones does not work

    1. Open the Start menu and select Settings.
    2. Select System.
    3. Select Sound.
    4. Scroll down to the Advanced menu and select More sound settings.
    5. In the Recording tab, select Headphones, and click Set as Default Device.
    6. Select OK to close the setting screen.

    If the above settings do not work, try the following:

    1. Turn the headphones off and then on again.
      Note for Truly Wireless headphones: To turn off the headphones set them in the charging case, close the lid, then remove them.
    2. Restart the computer.
    3. Reset the headphones.
    4. Initialize the headphones.
      Notes:
      • Initialization returns the headphones to the factory settings and all Bluetooth pairing information is deleted. After Initialization, delete the pairing information from the computer and perform pairing again.
      • If you have connected to the computer with the headphones named LE-xxxxx (model name), the headphones are paired with the computer with Low Energy mode and may cause the Bluetooth connection to fail or unable to hear the sound from the headphones. To avoid this, pair the headphones named without LE-xxxxx. If only LE-xxxxx is displayed when pairing, wait for a while to display the model name without LE-xxxxx.
    5. If you can use a different app or computer, check if the issue is resolved when connected with them.
