My brother bought a pair of the Beats "Solo" for my nephew for Christmas. Mainly because he wanted the lime green color. I was able to listen to them at length.
They have a very heavy, boomy, blotted bass response. They were also kind of bright in the highs. The mids were okay, but overall, I thought they sucked. I sure couldn't listen to them for more than a few minutes.
For the money, the Audio Technica ATH-M50 are excellent. I also would like to hear the new Woodtone headphones. They look pretty cool.
