The highly complex, double-symmetrical design of the Excellence headphone extension cable, combined with the high-density shielding mesh, protects the delicate audio signals as effectively as possible from external interference, such as that from smartphones or other electrical devices. The silver-plated conductors transport the analog music signal precisely and allow for an extremely dynamic and crystal-clear sound, especially with high-resolution audio formats. The 24k gold-plated contacts ensure optimal connectivity and minimal contact resistance for lossless transmission of the music signal.
