The Beats are not bad by any means. In fact, for bass heavy music (Hip-Hop, electro, etc) they are pretty good if you get the full sized one's.
For the price, if you only care about sound, the Senn HD-25 would be a better alternative with a similar flavor. Only problem is that they are ugly and look like they cost $20, not $200.
And that's partly the reason why the beats are successful, they are the full package. Sound decent, most people think they look good and are convenient.
Most of the recs you'll get will not have those three things. Some will sound good and look like crap and some others will sound underpowered unless you use a 1/4" jack and a headphone amp, thus making them a pain in the ass and far from convenient.
If you look at the Beats, you should also look at the B&W P5. Aesthetically pleasing, good sound (though not bass heavy) and designed to be portable and convenient.
