How to check if the DSEE HX or DSEE Extreme function is active on the headphones

Although I turned on the DSEE HX or DSEE Extreme, I cannot confirm if it is enabled during the music playback.

    In the Sony | Sound Connect app, open Device settings → Sound Quality/Volume, then you can turn on the DSEE HX or DSEE Extreme function. Once enabled, you will see DSEE HX or DSEE Extreme displayed under the headphone model name on the Sony | Sound Connect app dashboard.

    Note: The DSEE HX or DSEE Extreme function will be disabled when you connect the headphones to a playback device using the wired connection, or when you are playing a High-Resolution (Hi-Res) audio file.
