I use this to hang my (rather heavy) gaming headphones on the edge of my computer desk. It protrudes quite a bit, which is a good thing if you have headphones with a broad headband.
My headphones are, like previously written, quite heavy but this thing has proven faithful without being readjusted even once in months. It is starting to come loose a bit but that is because I have accidentally bumped into it while walking (so don't place it in an area that gets a lot of traffic).
The adjusting screw is long, meaning that this holder can be placed on both thin and thick desks.
Yes, I do recommend this headphone holder.
