Description

The Sennheiser MM 445 is a premium dynamic microphone capsule built for vocalists who demand exceptional clarity, presence, and feedback rejection on modern stages. Designed with a high-rejection supercardioid polar pattern, it offers focused sound capture while minimizing ambient noise and feedback, even in high-volume environments.

Its lightweight aluminum-copper voice coil ensures fast transient response and increased sensitivity, while the large diaphragm and tailored acoustic tuning deliver a rich, detailed vocal sound with pronounced proximity effect. Ideal for high-pressure live settings, the MM 445 is also engineered for durability, featuring a rugged metal basket and a spring-mounted capsule to reduce handling noise
