This is a headphone hanger, intended to mount on the wall with .8 mm diameter picture hanging screws. Instead of leaving your headphones lying around on your desk or in a drawer, you can hang them!
Find a place on a wall that would be a good place to hang headphones, drive 4 .8 mm screws through the 4 holes in the bracket and into the wall. Now hang some headphones!
