Neumann's WNS100 Windscreen 45mm (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.
The Neumann SG 21/17MT Microphone Swivel Mount is designed to mount miniature microphones to stands. The SG 21/17MT includes two clamps to accommodate different diameter sizes and the swivel joint provides left and right rotation.
