I have used these headphones before and i must say they are excellent, comfortable, and clamp like they are gonna break your skull. how ever upon ordering my own pair of these i was swindled by this dealer{{{ http://www.amazon.com/gp/browse.html?ie=UTF8&marketplaceID;=ATVPDKIKX0DER&me;=A1SPB9D2DMA0R4 }}}}} AKA yourdealDO NOT BUY THEM FROM THIS STORE THEY ARE COUNTERFEIT REPRODUCTIONS, they are very well made counterfeits but the head band is to thick, the cups are plastic versus metal, and the over all build quality is down the tubes. do your self a favor and find a reputable dealer.
