I have have these headphone for about two year . I want everyone to know that the sound be extraordinary . I still to this day have to check when listen that the volume be not turn up with my wife try to sleep . the sound be as close to sit in a movie theater as you be probably go to get . without the vibration of course . they be everything you could want in realistic sound , comfort , and battery life . this be where my accolade end however . I have notice another review say that he break at the swivel point where they adjust to the shape of you head . the same thing happen to I after about a year . when that happen they just kind of dangle from the head unit -lrb- oh , and yes , I be very careful with they -rrb- of course this seem to happen after the warranty have expire . well , I have refuse to reward the manufacturer for poor engineering at this point by another purchase . I use epoxy glue and bit of plastic to effect a repair . this be not bad but I also find that duct tape around that have help as well . I have be use they for about a year now . still great sound ! but if you be plan on buy these I think the manufacture could at least include some epoxy glue and duct tape with the purchase . they look stupid perhaps on my head but the sound be great !
