This adapter goes from a 3.5mm male connector on one end to dual (2) RCA female plugs on the other. These are commonly used for connecting a handheld audio device to larger speakers or to a home stereo system. It has color coded RCA plugs and is six inches in length, which is a great feature if you just need the adapter function and don't want to add a lot of length to your cable. This adapter cable is a durable, high-quality item that won't break or fall apart on you. It's also a great price and is backed by our FireFold Signature Lifetime Warranty.
