they do.
there's a technical term (which i never remember) which means that there's a constanting high pitched hiss/buzz that comes that only certain ears can hear... Bose has that. but it's not just a small minority, it's a LOT of people. i've had many a complaint about it...
they also just got a 14 year old junkie to come add a looaoaddd of bass to it, there's no massive engineering behind it, it's just bass bass bass.
the only thing you're paying for with bose headphones is the advertising. they pay apple, for example, millions and millions LITERALLY just to put their headphones on the shelves, and out for people to listen to them.
it's kind of subliminal, because about 70% of the people that praise them have never heard the sound quality before, they just see the name a billion times and think they must be good.
