This is convenient for connecting a microphone to a phone. Below is the manufacturer's introduction. Features E.D.GEAR microphone cables use 99.9% pure O.F.C. (Oxygen-Free Copper) wire for the core wire, achieving improved sound quality through high signal transmission. Furthermore, the use of Super Ω in the conductive vinyl reduces noise. Also, by applying an O.F.C. braided shield to the shield, external electromagnetic noise is cut off, and combined with the Neutrik plugs used in the cannon connectors, reliability is increased. In addition, the ECP series phone plugs for cannon-phone have 24-karat gold plating, improving sound quality. Detailed Information ■ Core Wire To minimize signal degradation, 99.9% pure O.F.C. (Oxygen-Free Copper) is used for the core wire. USA standard AWG#22 wire provides excellent sound quality. ■ Insulator Special polyethylene with low inductance, processed using a unique method, is used for the insulator. This reduces sound attenuation and loss. ■ Shield As a noise countermeasure, 99.9% pure O.F.C. braided shield is applied to the conductive vinyl (Super Ω), cutting off noise such as electromagnetic waves and radio interference, improving sound quality and reducing noise. ■ Sheath Ultra-flexible PVC is used for the sheath to increase the flexibility of the cable. It has few kinks and supports the player's free movement. It also supports use in low temperatures, performing even in cold regions (-10°C).
