The Sennheiser MM-445 is a supercardioid dynamic microphone capsule designed as a modular component for Sennheiser's evolution wireless 500 Series and certain other compatible handheld transmitters (like the SKP 500). This module provides a tailored vocal and instrument microphone solution in a wireless format, offering the sound quality and directional control of a high-end wired dynamic microphone integrated into a professional wireless system. Its supercardioid polar pattern delivers tighter front pickup and greater rejection of sound from the sides and rear compared to a standard cardioid, making it highly effective at minimizing stage noise and feedback, which is crucial for live performances in monitored environments.

The capsule is engineered to produce a clear, powerful sound with a pronounced presence boost in the upper midrange, ensuring vocals remain articulate and intelligible even when competing with loud backing tracks or instruments. It handles high sound pressure levels with ease, delivering a smooth frequency response without distortion. As a modular unit, the MM-445 screws directly onto the compatible wireless transmitter body, creating a seamless handheld microphone. This design allows performers or audio technicians to quickly swap different capsule models (such as the MM-435 cardioid or other specialty capsules) on the same transmitter, providing valuable flexibility to match the microphone to different voices or applications.

Constructed with a durable metal grille and robust internal components, the MM-445 is built to endure the physical demands of touring and frequent use. Its sonic character—focused, present, and with controlled low-end—makes it a reliable choice for lead and backing vocals, particularly in pop, rock, and gospel genres where clarity and projection are paramount. By combining the convenience of wireless operation with the proven acoustic performance of a dedicated dynamic capsule, the MM-445 serves as a key component for performers who require both mobility and professional-grade sound reinforcement.
