This metal holder is "made in Germany" and quite honestly, it shows when you hold it in your hand: heavy and robust, seems indestructible - because you pay the relatively high price like! Personally, I think the 4 holes for wall mounting somewhat exaggerated (2 screws rich also, so a headset is not so difficult), but one does not have to "fill" all;) The contact surface is very wide - even my widest Headset loose there place. The advantage is that the headphones (and because there are so thoroughly models in 4-digit price sector) far enough away from the wall hangs, avoid touching the ear pads the wall. The only point could complain about the one were the lack of mounting material (plugs / screws), just as there is already common in many articles. Mir is indeed rather personally, because I like to choose the screw itself (depending on the mounting subsoil), but I do not want to mention :)
