There is a feature of sound adjustment: it is separate for headphones and for the sound source. That is: For maximum volume, you need to unscrew the sound both on the headphones - through the buttons on the case - and on the source device (phone for example). This should be taken into account if you plan to adjust the sound only through the headphones so that it does not turn out to be too quiet or too loud.
