Pocket Earbud Holder

This is an earbud holder I designed to hold my Sennheiser MM30i headphones but it should work for a lot of different earbuds. I wanted it to be simple without complicated latches or a gotta-do-it-this-way winding order, and I wanted the exterior to be smooth so it felt nice in my pocket when I'm using the headphones.

There are two holes at either end of the recess which allow the earbuds to be stored face down to protect the tips. There is a notch where the wires come out and you wrap once,
