The 4-Pole 3.5mm Audio Cable is engineered for high-fidelity stereo sound transmission. Its robust shielding, including a silver-plated copper conductor, TPE jacket, and nylon braid, minimizes electromagnetic interference and ensures stable, noise-free audio. The 24K gold-plated plugs facilitate faster signal conduction and prevent audio delay.
