I twice pinched myself trying to expand the grippers. Other than that, it works well for headphones and the fact you can use it above your desk or below is pretty handy. Would work on a bookshelf or stand alone shelf too. I'd probably still buy this again despite the pinches because otherwise it is pretty good and the price is reasonable. (If you don't like pinches, be very careful or buy the sort of hook that has a tightening wheel.
