You're flat out wrong, in many, many ways. I started concentrating on sound quality back before i was even old enough to drive, with my dad (who used to play guitar and piano) and filled our house with Marantz equipment (in the day when that was the cream of the crop). To be honest though, I'm not here to give you a life story about me, i don't care if hold my opinion with a grain of salt or as the end all be all statement of the equipment.
You are right about one thing though, I did (fairly recently) google and research online about Dre Beats...my nephew asked for a pair for christmas last year and i personally didn't really know much about them outside of the general consensus that they were overrated. It was as easy as asking him what he wanted in the headphones though, and his short answer was that they looked cool...and that made them perfect for his use.
For what it's worth, my wife is a locations manager and film producer...and we do have a post production "studio" in our house (which is really just an office with two iMacs in it, about $30k worth of camera equipment...more hard drives than i care to count...and yes, a few sets of pretty high end headphones.) All that said though, my headphones were not a result of any of her gear, I got them for a good price and felt they sounded a world better than any of the other headphones in the bracket (the Beats weren't even out yet, but having compared them now, it still holds true).
