I cannot adjust the volume of the Truly Wireless Headphones.

    Use one of the following methods to adjust the volume.

    Assign the playback volume adjustment function to the touch sensor of the headphones

    IMPORTANT: Sony | Headphones Connect app version 6.0.0 (or later) is needed to use this function. If your model is WF-1000XM3, update the software of the headphones version 2.0.2 or later.

    The procedure below shows how to change the assigning function for the left unit from Ambient Sound Control to Volume Control.

    Note: The example images below are of the Sony | Headphones Connect app for Android smartphones and the WF-1000XM3 headphones. If you use an iPhone, the screen layouts will differ slightly.

    1. Open the Sony | Headphones Connect app.
    2. In the System tab, tap the (settings) icon at the bottom of the Change the touch sensor function.
    3. On the Left unit settings, select Volume Control.
    4. Check that the Function has changed to the Volume Control, and tap Done.
    5. Check that the Left unit of the Change the touch sensor function is set to the Volume Control.

    Adjust the volume on the playback device connected via Bluetooth

    When making a call, you can adjust the volume as necessary on the playback device connected via Bluetooth.

    Adjust the volume on the Sony | Headphones Connect app

    Install the Sony | Headphones Connect app, then change the volume using the app.

    Move the slide bar with the volume icon to change the volume level

    Note: On a device that can be linked with the headphones, you will have the ability to change volume level of the headphones using that device. You will not be able to change the headphones volume on a device that cannot be linked with the headphones.
