The Noise Canceling effect is weak or not working (LinkBuds Fit)

    Follow these steps to troubleshoot this issue:

    Before you start

    If the issue only occurs during a phone call, refer to the Noise canceling doesn't work or white noise is heard during a call on the headphones article.

    Solution

    1. Activate the Noise Canceling function.

      While wearing the headphones, press the L (left) side button or the area near your ear twice to turn on the Noise Canceling function. You will hear a notification sound from both sides at the same time (or from the left side when only the left is worn).
      Note: In the default setting, you can switch between the Noise Canceling and Ambient Sound functions by pressing the L (left) touch sensor.

      Hint: You can view a video on how to use the Noise Canceling function.

    2. Change the headphones settings using the Sony | Sound Connect app.

      When the Adaptive Sound Control is set to On, the headphones detect your action (running, walking, etc.) and automatically switch the settings of the Noise Canceling function to Ambient Sound Control. To make maximum use of the Noise Canceling function, follow these steps to set the Adaptive Sound Control to off and adjust the Noise Canceling or Ambient Sound Control manually.
      Note: If the Adaptive Sound Control is set to On, the Noise Canceling is adjusted, and Adaptive Sound Control is activated according to your action.

      1. Turn off the Adaptive Sound Control.
        1. Connect the headphones and smartphone via Bluetooth, then launch the Sony | Sound Connect app.
        2. In the My Device tab, check the Adaptive Sound Control status. If the status shows other than Off (Staying, Walking, etc.), select right arrow on the right side of the Adaptive Sound Control menu.
        3. Turn off the Adaptive Sound Control.
      2. In the My Device tab, select Device settings → Sound tab, and select Ambient Sound Control to adjust the setting. Tap the down arrow on the right of the Ambient Sound Control menu and select Noise Canceling.

    3. Fit the headphones to your ears firmly.

      If the earbuds do not fit your ears, the Noise Canceling function may be significantly affected. To maintain the quality, consider these factors:

      • Make sure that headphones are worn properly
      • Select the earbuds that best fit your ears. Measure the air-tightness of the earbud tips and find the optimal size of earbud tips using the Sony | Sound Connect app
      • Make sure that the headphones' microphone and your ear are not in contact with each other.

      For details, refer to How to wear the headphones properly and select the most suitable earbud tips article.
