these are great. got mine off of whiskeyy militia for 17 bucks last year and they are still working great. these are usualy $80 so $49 is pretty good. when the bass is up all the way you can feel the bass literaly vibrate your head. if you put the bass on and put the headfones on your back YOU WILL GET A MESSAGE. these are great really, but sometimes they run out of batteries kinda fast.
