Dr. Dre, Eminem, and other hip-hop luminaries have pushed their own headphones, and rapper 50 Cent is now working with Sleek on his model.
The Sleek by 50 headphones are still in production, so there were no test models at CES, but Sleek says it has built-in volume control, 60 feet of wireless range, and 10 hours of battery charge. A cool feature is the multi-listener opportunity, which lets four Sleek headphones sync up and listen to one audio source.
Sleek by 50 will be out later this year. Price is yet to be announced.
