One thing you need to know, is that this wall mount will not work on just one stud. The recipient thought they were darling, but more importantly she found them very comfortable. Grado, third party alternatives to the OEM pads are very limited. The front rail is at its maximum length just short of sun roof opening. Its made from fairly cheap materials - OSB and a plastic-y feeling metal for hooks, but its sturdy enough and holds a bunch of keys with no problem. I prefer male vocal on the hd600 because it sounds fuller, and I prefer female vocal on the Ety because it sounds sweeter. Putting them on was very simple. Its nice that there are several layers of hooks so as I get trimmer I can pull it in more tightly. I had been looking for black sandals for an upcoming wedding. These are made poorly now.
