I put this headphone stand together today with Unistrut, 1/2 inch hardware, and electrical parts. It has a very industrial look to it. I love playing all sorts of music through my K702s, but heavy metal and industrial is what this stand is all about. It probably weighs 25 pounds and if anchored in concrete could support headphones up to 500 pounds. I may make the 3" EMT (pipe on top) longer someday to accommodate his and hers K702s, although, I haven't figured out the "pink" mod for my wife's LOL. Comments welcome!
