The first news of a 50 Cent headphone line came at CES 2011, where the hip-hop mogul announced a partnership with Sleek Audio for the Platinum line of wireless headphones. Just a few months later Sleek confirmed that the parties had terminated their agreement, and it was revealed that 50 started his own company, SMS Audio, to make a full line of audio products. The Sync by 50 is the company’s first headphone offering, featuring an ostentatious design and Kleer wireless technology — just as the Platinum line was supposed to. The $400 headphones are set to go head-to-head with the venerable Studio Beats and Wireless Beats by Dre, but can 50 beat the Doctor at his own game?
