Compatible with most devices with a 3.5mm interface: For wide-ranging use. Solid long-grain copper conductors: Help reduce distortion. Foamed-polyethylene insulation materials: Minimize timing errors and soundstage smearing for enhanced clarity. Asymmetrical, double-balanced geometry: Delivers low impedance to provide rich, vibrant sound. Metal-layer noise-dissipation system: Helps limit RF and EMI noise for optimal performance. Connect a wide range of audio electronics with this AudioQuest Evergreen 3.5mm Mini analog interconnect, meticulously designed for outstanding flexibility and versatility. Solid Long-Grain Copper (LGC) conductors minimize distortion, Foamed-Polyethylene insulation preserves dynamic contrasts, and a Metal-Layer Noise-Dissipation efficiently dissipates high-frequency noise for cleaner, clearer, more naturally beautiful music.
