Neumann KK2105S Microphone Head for Sennheiser Wireless Systems (Black)

The Neumann KK2105S is a supercardioid microphone head engineered for integration with Sennheiser wireless systems, delivering studio–grade signal integrity in mobile and live applications. Neumann's heritage in precision transducers translates here into tight off–axis rejection and clean gain structure–critical for stage monitoring, host commentary, or embedded vocal capture in DJ and live production setups where electromagnetic interference and ambient noise are constant obstacles.

Built to withstand demanding performance environments, the KK2105S handles maximum SPL ratings of 150 dB (0.5% THD) and 155 dB (3% THD), making it capable of managing hot vocal lines without distortion. The supercardioid pattern narrows the pick–up window to roughly 90°, minimising bleed from monitors and competing audio sources. Sensitivity sits at 1.3 mV/Pa (−58 dBV/Pa), with noise floor of 33 dB–A and signal–to–noise ratio of 61 dB–A—specifications that prioritise transparency across the 80 Hz to 20 kHz band. At 257 mm length and 325 g total weight including transmitter, the head balances reach and durability without introducing fatigue during extended DJ sets or production sessions.

This capsule integrates seamlessly with a broad ecosystem of Sennheiser wireless bodies, including evolution wireless G3 and G4 series, as well as legacy 2000 and 3000 systems. Compatibility spans vocal transmitter platforms and instrument bodypacks, making it a versatile replacement or upgrade path for touring DJs, MCs, or festival performers who depend on proven wireless reliability and predictable tonal character night after night.
