I have had a brainwave headphones hanger for several years. Upon moving house I purchased myself a gaming desk for my study. I decided to have all my headphones in one place so purchased two of these to have three hangers stuck under my new desk.
I actually prefer this to my more expensive brainwave hanger, as the rubber tip ends with cable slots are really handy to keep it all neat and tidy. So I use the two new ones for my wired headphones and the Brainwaves for my wireless headphones.
Just one tip and I am sure you all know it anyhow, if it will not harm the surface you are intending to stick this hanger to, I recommend wiping the area you are going to stick it to with surgical sprit before sticking. It really does make a massive difference to the adhesion. On one of my hangers I have a pair of old Razor Shark gaming headphones (the heaviest headphones I have owned) and my V Moda M200 (the v moda are in their protective carry case) yet having prepped the surface with 99% isopropyl alcohol, the hanger fixing is solid several months after fixing in place.
