Sennheiser MZW 44 BK, Foam Windshield for Headmic 4, Black

Sennheiser MZW 44 BK Foam Windshield

The Sennheiser MZW 44 BK (Article Number: 700097) is a premium, factory-original replacement foam windshield designed specifically for the ultra-small KE 4 cardioid microphone capsule found on the Sennheiser Headmic 4 headset series. This acoustic accessory is an essential tool for live sound engineers, broadcasters, and theater technicians looking to maintain immaculate audio quality in challenging acoustic environments.

The Black version features a deep matte black finish, optimized to visually disappear on matching black Headmic 4 boom arms or blend discretely into dark theatrical staging and costuming.

Key Architectural and Acoustic Attributes

• Optimized Plosive Diffusion: The windshield utilizes a highly porous, specialized open-cell acoustic foam density. It breaks up fast-moving air turbulence from heavy breath exhales, sighs, and hard plosive consonants ("P", "B", "T") before the air blast can strike the sensitive microphone diaphragm and cause low-frequency clipping.

• Acoustically Transparent Engineering: Unlike generic, dense foam covers that muffle or darken a microphone's tone, the MZW 44 BK is mathematically tailored to retain the pristine high-frequency definition and natural presence of the KE 4 capsule. It maintains a flat frequency response with virtually unmeasurable high-end attenuation.

• Debris and Moisture Shielding: Beyond wind protection, the foam structure acts as a vital defensive barrier. It intercepts stray sweat droplets, spit, spray, and pulverized theatrical stage makeup, preventing foreign particles from settling into the micro-ports of the cardioid capsule housing.

Performer Deployment and Care Advice

Ensure a Flush Mechanical Fit: When sliding the MZW 44 BK onto the tip of the Headmic 4 boom arm, gently guide it all the way back until it snugly seats over the entire capsule capsule housing. Leaving a gap or letting the foam sit loosely on the tip can create an internal air pocket that traps low-frequency resonance or lets wind noise bypass the protective layer.

Hygienic Maintenance and Swapping: Because headworn windshields live in close proximity to a presenter's mouth, they naturally accumulate moisture and bacteria during a performance. Never store the headset away with a damp windshield attached. Gently slide the foam off after a show, rinse it with warm water (no harsh soaps), let it air-dry completely, and rotate fresh spares across your multi-show talent lineup.
