Sweet baby jesus don't go to Head-fi. lol, I went, and my wallet cried for a few years. actually my wallets still crying.
Honestly, yes bose is over rated in the sound category, but I find it hard to find any better noise cancelling ones. I have a pair of ATHANC7's and they do the job, but the bose QC15 and QC3 are much better at noise cancelling than the ANC7's, as for sound quality, I'd say both headphones are just average, and there are MANY cans that totally blow them out of the water, but in terms of noise cancelling, i'd say the bose ones are great.
That being said, I haven't tried much else other than the beats, and some crappy ones from philips? or was it panasonic (i don't rmb tbh).
