Neumann's WSS100 90mm Windscreen Max Attenuation in 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 KK 105 S and KMS 105/140/150 microphones.
