Sennheiser KA 600 Coiled Microphone XLR to 3.5mm (40cm Stretched)

The Sennheiser KA 600 is a coiled XLR-to–3.5mm adapter cable designed to bridge professional microphones to consumer audio inputs. Built by Sennheiser, this 40cm cable connects XLR female connectors to 3.5mm TRS male jacks, enabling direct microphone feeds to cameras, portable recorders, and mixing devices without phantom power. The coiled design stretches to 40cm while remaining compact at rest.

The cable measures 10cm unstretched and extends to approximately 40cm when gently pulled, falling within Sennheiser's design tolerances. Its XLR female end accepts standard professional microphone connectors, while the 1/8-inch TRS male jack fits 3.5mm mic inputs found on DSLR cameras, mirrorless bodies, and portable audio interfaces. The shielded construction minimises interference, though users should note this cable does not deliver phantom power—battery-powered microphones or external preamps are required for condensers needing it.

Field recordists favour this cable for attaching shotgun mics to cameras, wireless boom operators use it to connect transmitter outputs to camera inputs, and studio engineers employ it to route XLR–sourced signals into line-level inputs on mixers or audio interfaces. Bedroom producers often patch it between mic preamps and compact recorders. The coiled format keeps cable runs tidy on crowded rigs whilst remaining long enough for flexible mic placement away from camera bodies.
