Can’t get the music in the headphones loud enough

1. Turn up the device volume all the way.  In the audio settings of your phone/tablet/laptop, turn the volume to maximum.
2. Turn up the software volume all the way. In the Spotify, Apple Music or whatever streaming plateform you are using, turn up the software volume in the user interface all the way.
3. While doing this, turn down you headphone volume to about 50%.   That way, your dancers will be able to turn up much louder during the peak excitement of the dancing time.
