Sennheiser HMD 46/ HME 27 - Windscreen 1 pc Windscreen for HMD 46, HME 27

Sennheiser HMD 46 / HME 27 Windscreen

The Sennheiser HMD 46/HME 27 Windscreen (Article Number: 543656) is a factory-original, premium original equipment manufacturer (OEM) replacement foam windshield designed specifically for the boom microphone capsules found on Sennheiser HMD 46, HME 46, and HME/HMD/HMDC 27 series professional broadcast and air traffic control (ATC) headsets.

As a vital acoustic and hygienic maintenance accessory, this individual foam windshield is a standard requirement for outside broadcast (OB) trucks, television studios, radio control rooms, and command-and-control facilities running fleets of Sennheiser communication headsets.

Key Architectural and Acoustic Attributes

• Targeted Wind and Pop Suppression: The windscreen utilizes a specialized, high-porosity open-cell acoustic foam density. It diffuses fast-moving airflow from mouth exhales, heavy breathing, and hard plosive consonants ("P", "B", "T"), suppressing turbulent pops before they can strike the capsule diaphragm and overload the channel.

• Acoustically Transparent Calibration: Engineered mathematically to preserve signal integrity, the open-cell structure prevents high-frequency loss. It ensures vocal intelligibility remains crisp and clinical, satisfying both critical broadcast standards and the extreme accuracy required for call-back aviation communication.

• Micro-Debris Defensive Barrier: Beyond managing airflow, the foam shell serves as a physical shield over the capsule. It intercepts stray saliva droplets, sweat, skin flakes, and atmospheric dust, preventing foreign particulates from settling inside the capsule ports.

Installation and Fleet Maintenance Advice

Tool-Free Slip Installation: Replacing the windscreen takes only a moment and requires no tools. Carefully peel the old, worn foam away from the boom arm capsule. Slide the fresh 543656 windscreen directly over the microphone housing, gently pulling it down until it sits fully flush and securely covers the microphone ports. Avoid pulling or twisting the foam excessively during installation to prevent accidental tearing.

Fleet Sanitation Protocols: Because boom microphone windscreens live in extreme proximity to operators' mouths, they naturally collect moisture, breath vapor, and bacteria during long broadcast shifts or ATC rotations. To maintain station hygiene across shared hardware, establish a routine to swap out or sanitize the foam tips between different users rather than reusing a damp or soiled windscreen.
