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.
