The highly complex, dual symmetrical structure of the Excellence headphones extension cable in conjunction with the very densely woven shielding protects the intricate audio signals optimally against external interference that is emitted from smartphones or other electrical devices, for instance. The silver-plated conductors transmit the analogue music signal precisely and enable exceptionally crystal clear and dynamic sound even for high-resolution audio formats. The 24-carat gold-plated contacts ensure optimum contact and minimal transition resistance for low-loss transmission of the music signal.
