Rapper 50 Cent is teaming up with basketball star Carmelo Anthony for a new line of headphones. 

The rapper's headphone company, SMS Audio, has announced the launch of its new Sports Collection.  Built for active lifestyles, the new headphones will give listeners a choice between wireless and wired models. 

In a statement, 50 says the headphones will "hold up" against any sort of physical activity.  He adds that sweat-proofing the headphones was something his partner Carmelo Anthony believed was missing from other high-end headphones.
