This listing is for a Red Beats 3.5mm aux cable. Came new with my headset - never needed.  Had plenty of 3.5mm cables already.  

This cable is very durable, lightweight, reliable, and is compatible with lots of other brands, including Panasonic, Apple, and Samsung, just to name a few. The design is male to male connectors, suitable for use with headphones and devices featuring a microphone. Works great.

Did unwrap it to measure length, and no, I'm not as good as a machine at wrapping it perfectly.
