The MU1MMFS 3.5mm headphone extension cable (1m) features a 3.5mm (1/8" TRS) male audio connector on one end and a 3.5mm (1/8" TRS) female audio connector on the other, making it easy to extend the reach of your headphones between your iPhone®, MP3 player or other mobile audio devices and your stereo system.To ensure long-lasting performance, this high quality headphone extension cord features molded PVC strain relief at each of the 1/8" TRS connectors , which prevents the cable termination points from bending at sharp angles, in turn reducing the risk of cable damage.
