4-Pole 3.5mm headset extension cable (1m) features a 3.5mm (1/8-in TRRS) audio connector on one end and a 3.5mm (1/8-in TRRS) audio connector on the other, making it easy to extend the reach between your hands-free headset or headphones, and your iPhone, mobile phone or laptop computer. To ensure long-lasting performance, this high quality 3.5mm audio extension cable features molded PVC strain relief at each of the 1/8-inch TRRS connectors, which prevents the cable termination points from bending at sharp angles, in turn reducing the risk of cable damage.
