The sound is all you could want but these literally fell apart in nine months. They are only connected by a flimsy nut and bolt into plastic that holds the full weight of very heavy phones. That bolt comes loose, off comes the headphone. Repair the left side for $100 in two weeks and then the right side falls off because the phones need to both be bolted down tight to hold together. After I spent $225 fixing them they just fell apart yet again a week later. Folks saying these are well built are either lying through their teeth or haven't had them long enough. Do not waste your money. Four star sound, no star construction. Ripoff.
