I am currently working on my desk setup at home. I order these with the intentions of using them to hold the wires from my headphones. I wanted to hang my headphones from a hook and then loop the attached wires around these. However, when these came that were bigger than I thought. They are big enough to hand your headphones from on their own. The magnets are super strong and I don't anticipate that the would have any problem holding up the heaviest set of headphones. The hooks are about 1.5" tall from base to tip. The usable area where your item would rest is about 1.25" long. The hook itself is some type of plastic or acrylic. This wouldn't hold a backpack of books but a 2 or 3 pound item would be no problem for these. I recommend them.
