Twisted pair oxygen-free copper wire and foamed PE dielectric are optimized to fight noise and hum, and deliver excellent sound quality and audio signal transmission. The cable's bonded construction is designed for neat, easy connection of audio signals. The low loss 100% foil and spiral-wound oxygen-free copper (OFC) shielding protects the delicate signals from electromagnetic interference (EMI) and radio frequency interference (RFI). Color-coded molded connectors and an ultra-flexible jacket enable easy installation. Corrosion-resistant 24K gold-plated heavy-duty contacts ensure a lifetime of performance.
