"The good: The Beats Solo by Dr. Dre Headphones from Monster offer a stylish, compact, and durable design that lends itself well to on-the-go use. The cable is ultranice and features an integrated mic, iPod controls, and volume rocker. Bass is thumping, and the package includes a handy carrying case.
The bad: The Beats Solo headphones may not be comfortable for everyone, audio is muddy overall, and they leak a fair amount of sound.
The bottom line: The Beats Solo by Dr. Dre Headphones from Monster offer a killer, travel-friendly design that's sure to turn heads, but the audio quality fails to live up to the price tag."
Spend the $$$ and get the QC15s IMHO.
