SLAM DUNK: The latest offering from Jimmy Iovine and Dr. Dre’s smash hit Beats headphone line is LeBron's PowerBeats headphones, a collaboration with you know who. Said Dre in a statement: "We worked with LeBron to make sure these would be the ultimate headphones for athletes. I'm always about the performance, the sound, and LeBron brought what he needed in terms of function to the table. I've been wearing the prototype for PowerBeats in the gym every day for the last few months, so I can honestly say they're the best headphones for working out." (10/1a)
