Sennheiser MZW 4032-C Foam windshield for MD 425 and MD 431 II and evolution vocal mics, Blue

Sennheiser MZW 4032-C High-Density Foam Windshield (Royal Blue)

The Sennheiser MZW 4032-C (Official Article Number: 002980) is a professional-grade, high-density open-cell acoustic foam windscreen designed exclusively for handheld vocal, stage, and interview microphones. While standard windscreens feature low-visibility dark charcoal tones, the "-C" designation specifies its factory coloration in a vibrant Royal Blue. This model is heavily utilized by news networks, sports broadcasters, field journalists, and live stage managers to quickly separate and identify primary talent microphones on camera or in multi-microphone stage arrays.

The interior chamber features a specialized grooved design that allows it to conform securely over a wide variety of Sennheiser's iconic vintage and modern handheld microphone baskets without slipping or compressing.

Key Acoustic and Aesthetic Attributes

• Vibrant Visual Identification Profile: The high-visibility blue finish is optimized for television broadcast, outdoor electronic news gathering (ENG), and live multi-vocalist touring sets where instant tracking of specific mic channels is visually critical.

• Grooved Interior Security Fit: Unlike generic aftermarket slip-on foam socks, the interior wall is engineered with precision-molded grooves. This design matches the contours of Sennheiser evolution and flagship dynamic capsules, ensuring a tight friction seal that won't twist or fly off when a performer moves dynamically on stage.

• Premium Acoustic Plosive Dispersion: Made from highly calibrated, open-cell polyurethane foam. It disperses high-velocity air streams from vocal breath pops ($p$, $b$, $t$ plosives) and outdoor wind drag, while remaining completely transparent to incoming audio frequencies. It protects speech intelligibility without dulling high-end presence.

• Diaphragm Moisture Shield: Serves as a reliable baseline protective block that intercepts heavy saliva, sweat, and condensation from "mic-eating" performers, preserving the sensitive dynamic or condenser element inside from corrosion or humidity short-outs.

Field Operation and Maintenance Advice

Installing Smoothly Over the Basket: To seat the windshield onto your microphone capsule without tearing the interior polyurethane substrate, do not slam it down with force. Instead, grasp the lower collar of the blue foam and slide it over the metal mesh head with a gentle, slow clockwise twisting motion until the top curve of the basket reaches the internal roof of the foam chamber.

Sanitization Protocols for Vocal Hygiene: Because this foam sits directly against performers' lips, it will absorb makeup, sweat, and breath vapor. Wash the foam weekly by sliding it off the microphone and placing it into lukewarm water with a pump of antimicrobial dish soap or mild baby shampoo. Gently press the soap solution through the foam. Never wring, twist, or squeeze the foam aggressively, or you will tear the internal grooved guide paths. Rinse thoroughly and allow it to air dry completely for 24 hours before re-deploying it on a live, powered microphone capsule.
