Sennheiser MM 445. The black Sennheiser MM 445 is a dynamic, supercardioid microphone capsule, which thanks to its Sennheiser standard-capsule interface, is designed to mount on a broad variety of Sennheiser wireless handheld transmitters. The MM 445 features a supercardioid polar pattern that greatly rejects off-axis background noise, focusing audio capture tightly on the vocalist for extreme feedback reduction on loud stages. With a high-quality aluminum-copper voice coil, a hum compensation coil, a spring-mounted mechanism, and rugged metal basket, the capsule provides every voice with sophisticated transparency, richness in the lows and mid-ranges, and unparalleled acoustic intimacy that's ideal for demanding live-sound and broadcast applications.
