The headphones don't turn on (LinkBuds S)

    Follow these steps to troubleshoot this issue when using the LinkBuds S earbud headphones:

    1. Select your problem:
      One earbud does turn on, but the other one doesn't.

      Go to step 2.
      Neither side of the earbuds turns on.

      Go to step 4.
    2. Check if the Google Assistant or Amazon Alexa is set to the headphones.
      Note: When the Service Link feature is turned on using the Sony | Headphones Connect app, only the Right side can be used by itself.
      Google Assistant or Amazon Alexa is enabled.
      Go to step 3.
      These functions are not enabled, or you don't know if they are.
      Go to step 4.
    3. Make sure the touch sensor control function or Voice Assistant function is set according to the way you use the earbuds:

      When these functions are enabled, only the side with the touch sensor control function set to Playback control can be used by itself.

      • If you want to use one side of the earbuds by itself: Follow these steps to set the touch sensor control function of the desired side to Playback control:
        1. Open the Sony | Headphones Connect app.
        2. In the System tab, select (Settings) next to the Change the touch sensor function menu.
        3. Select the side you want to use by itself, either L (Left) or R (Right), and set the Function to Playback control.

        Note: When you assign Playback control to both sides, full functionality is only available on the Right side.

      • If you want to use either earbuds by itself: Set the Voice Assistant function to Voice Assist Function of Mobile Device. With this setting, either side of the headphones can be used alone.
        1. Open the Sony | Headphones Connect app.
        2. Tap  (expand) next to Voice Assist Function of Mobile device.
        3. Tap Voice Assist Function of Mobile Device or Do not use.
      After changing the settings, the earbuds turn on.

      The earbuds don't turn on.
      Go to step 4.
    4. Clean the charging ports of the headphones, and check the indicator of the charging case.

      Clean the charging ports on the earbuds and charging case. Then check the indicator on the charging case. For details on how to clean the headphones, refer to the How to care for the headphones article.

      Note: Do not use compressed air to remove dust as this can cause dust to get into the microphone or sound outlet holes, leading to malfunction.
