Why people don't get that the human ear can't actually detect sound "quality" differences beyond a certain point, making many of these expensive headphones obsolete, is a mystery to me. The most it does differently compared to maybe a nice thirty dollar pair (emphasis on nice) is sound different - but not actually better. Seriously, take some time to stop and think what you're paying $300 for - about an eighth of a pound of plastic, some copper (maybe gold-plated) wire, a tiny bit of metal, and a couple of magnets. Very rarely are there any complex electronic functions built in; it's just different magnets and different conductors being used - which I guarantee you don't cost anywhere near $300. I'm not beating up on anyone for spending money on headphones (I'm an audiophile myself); it just saddens me that people spend so much on something that's not worth the money when there are cheaper, but just as good, options out there.
