Rapper 50 Cent is teaming up with Carmelo Anthony for a new line of headphones. Fifty’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. Oh Boy, No More wet headphones.
