The Ambient Sound Control mode changes unexpectedly, or a notification sound is sometimes heard.

    IMPORTANT: This article applies only to specific products and/or operating systems. Check the Applicable Products and Categories section of this article before starting these steps.

    When the Ambient Sound Control mode changes unexpectedly, check the following:


    The touch sensor is tapped inadvertently (for Truly Wireless headphones with touch sensors)

    The issue may have been caused because the touch sensor was tapped inadvertently.
    If this happens frequently, you can disable the touch sensor by changing the function of the touch sensor to None Assigned using the Headphones Connect app.

    The image below shows the Headphones Connect app screen, using the WF-1000XM3 as an example.

    Adaptive Sound Control is set to On

    When the Adaptive Sound Control is set to On, the Headphones Connect app detects your action and adjusts the setting of the Noise Canceling or Ambient Sound Control. The notification sound tells you the moment when the setting changes. To keep this from happening, follow these steps using the Headphones Connect app.

    1. Turn Off the Adaptive Sound Control.
