The CFM VK is a balanced extension cable for 6.35 mm stereo jacks, for example for use as a headphone extension. The two hand-soldered REAN® by NEUTRIK®plugs are protected against damage by a sprayed-on anti-kink sleeve, the contacts are gold-plated and thus protected against corrosion. With a conductor cross-section of 0.22 mm² consisting of 28 x 0.10 mm strands made of high-purity copper, the cable ensures uncompromised signal transmission. A spiral shield protects against disturbing external influences and interference, for example through power supplies or power lines.
