The MU2MMFS 2m audio extension cable features one male and one female 3.5mm (1/8' TRS) audio connector, making it easy to extend the reach of your headphones / earphones between your iPhone, MP3 player or other mobile audio devices and your stereo system. To ensure long-lasting performance, this high quality extension cord features moulded PVC strain relief at each of the mini jack connectors , which prevents the cable termination points from bending at sharp angles, in turn reducing the risk of cable damage. Plus, the slim connector design fits into most audio devices even while inside its protective case. The MU2MMFS is backed by StarTech.com's lifetime warranty, for guaranteed reliability.
