What Celebrity displayed a new line of headphones at CES?

It seems to me that coming out with your own line of headphones is the next trend for Celebrities these days. You have Jay-Z who joined Dr.Dre, Lady Gaga, Diddy and Eminem who are just a few of the celebrities who now have their own line of headphones.

At the 2011 CES, 50 Cent showed up promoting his own line of wireless headphones.  Most just rolled their eyes thinking another celebrity rocking some new headphones.  The new headphone line is called "Sleek" which has a few different features that may make this line stand out compared to the other celebrity lines.  The Sleek headphones are wireless and have a 60 ft wireless range and a 10 hour battery life.  Many lucky customers got the privilege of meeting 50 cent with the purchase of these headphones at CES.  We will see how the Sleek line matches up to its competitors this year.
