Neumann KK2105S Microphone Head for Sennheiser Wireless Systems (Black)

The Neumann KK 2105S is a wireless capsule head engineered for integration with Sennheiser systems, carrying Neumann's reputation for precision audio capture across studio and live contexts. Built on a supercardioid pick-up pattern, this capsule delivers focused rejection of ambient noise whilst maintaining clarity across an 80 Hz to 20 kHz bandwidth. At 325 grammes including transmitter and power supply, the unit balances portability with robust engineering—a critical consideration for touring musicians and studio recordists managing wireless workflow.

The capsule demonstrates low equivalent noise at 33 dB-A (A-weighted) and achieves a signal-to-noise ratio of 61 dB-A relative to 94 dB SPL, metrics that translate to clean, articulate vocal and instrument capture even in moderate ambient conditions. Maximum SPL handling reaches 155 dB at 3 per cent THD, accommodating close-miked sources without distortion. The 48 mm diameter and 257 mm overall length position the capsule as a discreet addition to most wireless bodypacks, whilst sensitivity of 1.3 mV/Pa maintains headroom across typical vocalist and instrument applications.

This capsule integrates across Neumann's extensive wireless and wired microphone catalogue—models including the KMS 104, KMS 105, KM 184, U 87 Ai, and TLM 103 share compatible mounting infrastructure. That compatibility breadth means studios and touring rigs can standardise capsule performance across multiple channels and contexts without reconfiguring wireless systems or purchasing new transmitter hardware.
