Neumann's WS100 90mm Windscreen  (Black) is an open-cell polyurethane foam which attenuates close range sounds, wind, and fast movements of the microphone boom.

The wind noise attenuation was measured without electrical filtering in a turbulent air stream traveling at 20 km/h, generated by a noiseless wind machine.

This windscreen is designed specifically for the KM 100 and Series 180 microphones.
