Music mogul 50 Cent has taken his passion for quality sound into the high-end headphone market with his company, SMS Audio. Now, he's partnering with Intel on biometric headphones that incorporate wearable technology and fitness tracking, something he believes sets it apart from the competition. His main competitor is Beats, which already owns 62% of revenues in the high-end headphone market, according to NPD Group. After Apple's $3 billion purchase of Beats, 50 tells TheStreet's Brittany Umar whether an acquisition of SMS Audio could be next. He also sheds light on how he's building his brand outside of the music industry through a variety of ventures.
