well , I have no frame of reference as far as high-end headphone go , but these be by far the best headphone I have ever own . I be go to get the bose tri-port , but the review be bad , and I be look for a open design that still cover the ear . these be really comfortable when I do not have my glass on . they get a little uncomfortable after a while because of my glass , but what can you do ? they sound AMAZING . I could never tell the difference between mp3 and aac , now I definitely can , and I be convert everything in my iTunes library to AAC . I think the 9 foot long cord be way too much -lrb- it be cool to be able to plug directly into the back of my computer rather than plug into the staticy speaker , though -rrb- so I use a garbage bag twist-tie to bunch some of it up -lrb- which be not a inconvenience if you bunch it up in the middle , neither too close to the headphone nor too close to the plug -rrb- . the cool thing about the cord be that it be detachable ... I just do not know how to find a shorter version of this exact cord with which I can replace it . I burn they in -lrb- play a variety of musical style through the headphone for hour and hour when I first get they -rrb- or whatever -lrb- ... I be not sure if I do it correctly . oh well , they still sound great . -rrb- and the treble , mid , and bass all seem to be fine . I be hear thing I have never hear in some of my favorite song -lrb- ironically , I hear whisper vocal that speak of `` subtle detail '' in `` the Lemon of Pink Pt . 1 '' by the book -rrb- . my only complaint be I do not like silver . I be never go to understand why any headphone on earth have to be silver . I guess black plastic get hot in the sun . . but they generally look better , in my opinion . anyway , these be the best pair of headphone I have ever own and they only set I back thirty-five dollar .
