A lot of bassy headphones (like Ultrasones or Denons) have very quick, punchy, detailed and precise bass. And while they do sacrifice a bit of highs and mids from time to time, they still have detailed highs and mids. The Beats have flabby and slow bass, and no mids or highs whatsoever. Usually that is a sign of cheap equipment, something you shouldn't see in headphones that cost in the hundreds of dollars.
A good example, a friend of mine recently got the Monoprice 8323's, and when comparing them to his friend's Beats Solo HD ($200 headphones), said they sounded almost the same.
Thing is, the Monoprice 8323's are - I kid you not - $20.
The Solos are not *that* bad. But for $350 they are. For $50 they'd be a decent deal.
It's not that surprising, these headphones come from Monster Cable, the company that is famous for selling $2 HDMI cables for $200.
