The only issue I have is that the Yahoo! article claims that it is "widely regarded as the best in the industry." Where are they getting that from? Near all reviews I've read, and from my own experience, indicate that they sound fine but there are better options out there at the price point. Furthermore, considering their target audience and price point, I find it inconceivable that they would even approach the sound quality necessary to be determined the best. That claim is just stupid and misguided.
That said, I have no issue with Mr. Ochocinco blowing $28k on headphones. He makes the money and he obviously thought it was a good decision and, so long as he's happy with it, I don't see any problem.
