50 Cent/SMS Audio

Unlike the SOUL by Ludacris headphones, a product that was created for the rapper by an existing company, SMS Audio is a legit start-up where 50 Cent serves as the acting CEO. When I met him at the Consumer Electronics Show in Las Vegas this past January, the popular actor and rapper spoke in great detail about the product's specs and the challenges of starting a company--especially the time it took to create headphones with distinct enough audio drivers to make his music sound lush and loud. But he also knows his high-profile stature gives him a leg up (his booth at CES was mobbed with fans eager to get a glimpse of the rapper in person).
