I will not judge you based on your taste in terrible films...
Also taste is not necessarily subjective.The higher your intelligence, the more likely you will have a trained ears/eyes/brain.
I'll try my best not to read that as an ill subliminal.
I'm not defending the Beats; I haven't tried them (unless the model I tried wasn't actually broken in which case, yes, they are quite bad). I'm just saying that everyone's looking for something different in a pair of headphones. And contrary to your claims, some very smart people like very bad music; see Robert Christgau's near-infatuation with The Black Eyed Peas (and, more defensibly, Shakira, who also apparently has a genius IQ). And let's be real: some audiophiles think USB cables have distinct sound signatures, so people can go nuts and follow the ill-informed pack irrespective of how they approach their purchases.
To a really significant extent Bose and Monster market more Apple-like products than the rest of the headphone industry (and just look what brands dominate the interiors of Apple stores); they don't focus on specs, but rather on aesthetics and the user experience. It is kind of backward that a premium product would be designed to sound good with music mastered to play well on the worst speakers, though.
I'm frustrated by the state of music, too. The internet did a lot as a platform for esoteric bands, helping them to gain notice; digital production and distribution techniques certainlly democratized the medium substantially. And the growing popularity of sample-based music has been spurred by an increase in music criticism readership and by iTunes playlists positing the listener as his or her own DJ: when the musician is also an avid listener we get cool albums about music. I'd say Daft Punk, Kanye West, and Girl Talk are all pretty awesome artists who've helped usher us into a potentially fruitful era of post-modern pop.
And yet attention spans have significantly decreased and so has sound quality. I spent way too much money on a high end pair of headphones, and I can't fully enjoy two of my favorite albums from last year (My Beautiful Dark Twisted Fantasy and King Night), because they're poorly mastered. Never mind that Kanye's opus undersold since its tracks are too long (and too interesting) to make effective singles, it sounds so bad technically that it's grating to listen to any of it. It's a great and wonderful mess of highbrow and lowbrow concepts, but it's also a not-so-great mess of highbrow masturbatory prog rock arrangements and low brow ****** sound quality...
The contemporary audience lacks an attention span. Bad earbuds necessitate poorly mastered music. The few interesting genres that have recently emerged are growing cliquey, insular, and sonically monotonous. There's a lot to be frustrated by in the state of popular music.
Still, great music persists even as new preferences in sound signature have developed. Go listen to Kanye West on your Beats by Dre. I'll listen to Joanna Newsom on my electrostats.
Maybe we can trade afterward?
