50 Cent talks headphones and the future of music

50 Cent: Blown away by Apple-Beats $3 billion deal

Curtis Jackson, aka 50 Cent, isn't just a multi-platinum rapper, he's also a successful entrepreneur with a range of businesses.

And now he's at CES to pitch the headphones from his company, SMS. In addition to a line of Star Wars-branded headphones—white ones look like the headphone version of R2D2—he's promoting SMS' Intel-powered fitness headphones which measure consumers heart rate, as well as how fast they're running.

SMS headphones are facing a whole new type of competition, now that the company's biggest rival, Beats, is owned by behemoth Apple. What does that mean for 50's business? He shrugged and said that's why he teamed up with Intel.

50 Cent also weighed in on the fast-changing music business. With Taylor Swift pulling her music from Spotify, and so many new ways consumers can find and listen to music, he called this "the Wild West."
