Snapback-headphones

I was sitting on the plane, my wireless headphones loosely hanging around my neck. Suddenly I thought, I always wear a cap, so I came up with this clever solution - a tiny device that perfectly fits flush with the snapback plastic on the back of my favorite cap. It might look a bit unusual, but it's actually made it much harder to misplace my headphones now.
