Near-perfect frequency response, double-insulated/double-shield coverage, and the lowest triboelectric (handling noise) of any cables on the market. The plug is soldered, covered with an internal copper shield tube, and then over-molded, first with a rigid PVC to encapsulate the solder joints, and then with a flexible polymer for unprecedented strain relief. This virtually indestructible, 14-gauge cable is so tough and so durable that it carries a manufacturer's limited lifetime warranty.
