The Beats sound VERY good on almost all sound stages, people that are complaining about not having highs need to hook them up to some better quality equipment/music formats. I am NOT saying that they are necessarily better or worse but until I hear the Bose on my Apple lossless music I have to say that I am very impressed with the Beats. I have to say that the "noise canceling" is ok, it's not great by any means. I would have to say from the demos that I have heard the QC15 IS better by far with noise canceling. Just my two cents.
