The CFM VK is a balanced extension cable for 6.35 mm stereo jacks for e.g. headphones. The two hand-soldered REAN® by NEUTRIK® connectors are protected from damage by a moulded-on anti-kink sleeve, the contacts are gold-plated and thus protected from corrosion.

The used bulk cable with a conductor area of 0.22 mm² consisting of 28 x 0.10 mm strands of high-purity copper ensures undistorted signal transmission. A spiral shielding protects against disturbing external influences and prevents noise from power supply units or power lines, for example.
