Unusual Headset Holder

I really wanted a headset holder but without hanging them up on the foam-part.
So I made one that holds it on the plastic borders without squishing or rubbing against the foam.

This is kinda made quick&dirty so work is still in progress.
It's just held by double-sided tape for now.
I also want to make this easy scalable for headsets with a larger top-part than my Sennheiser 600.
