I wanted a hanger bracket for my son's gaming set, but wanted something that did not have to be drilled into the desk and would match his desk. These earphone hangers came in a two pack that can be mounted via the included 3M adhesive strips (2 per hanger). I let the strips attach to the underside and side leg of the desk and waited a few hours before attaching the hanger bracket, like you do the Command Strips. The next day, I placed his headphones onto the hanger bracket and was very pleased that it holds his headset. I am very pleased with this purchase. The ABS plastic is solid black and precision cut with no sharp edges. Definitely high quality and I even have a spare! I did not realize the set came with two brackets, I was only expecting one. Overall, I am very happy with these and would love to see a white or clear option offered as well, so I could put one in my girls' room. These would be perfect for anyone wanting to mount a bracket for headphones to a piece of furniture without drilling.
