I be no audiophile or anything , I usually just go with the cheap behind the head headphone or something , but I get a promotion at work and very soon after someone sit on my old pair , so I figure I would replace they with something nice to celebrate . I look around for the best pair I could find for a reasonable price , and these seem like the choice . I be blow away by these - the bass response be incredible . I feel like I can hear every instrument that be playing , I can hear the bass like no other headphone I have ever experience , they be comfortable and the cord be long enough so I can move around at my desk and still be plug in . I do not think I have even begin to scratch the surface with these since I just plug it into my ipod , instead of a professional amplifier or something , and my audio bitrate be 128 or maybe 192 but man these thing be sweet . its hard to bring they to work since they be so large and I be afraid of break they -lrb- they seem sturdy but have the dj flip thing go on and I be a bit clumsy with my headphone -rrb- , but other than that these be a engineering marvel . if you do not have these , you have not really listen to you music yet .
