This headphone hanger will fit up to 110mm wide speakers, so that the headphones will hang straight down. This is a quite large headphone, measured after my Beyerdynamic DT990 Pro headphones. If your headphone speakers are wider than this is will just hang at an angle.
Remix with the step file if you wish!
The max headphone band width is 55mm
