The noise canceling in the studio line adds too much distortion and hiss but doesn't reduce noise by much and can't be run without it, that makes these a 100% pointless headphone in my eye at most any price. It's rather telling that this headphone's design went with the company that marketed it rather than the company that designed it.
I also suspect that a lot of the counterfeit Beats are just surplus production that the factory sells under the table. Most "how to spot a fake" posts/videos usually boil down to esoteric properties such as marketing booklets, they appear to have been produced by the same injection molds. You certainly can't spot a fake by sound quality. We're talking about headphones where the Chinese Knockoffs (Noontec Zoro) is better than the original.
my local shopping mall has a shop where they sell fake beats where their sound is almost the same as the genuine but they cost 1/3 the retail price, its a better deal, makes it become from absoloutely rediculesly overpriced shet to not good value, thats an improvement :P
