The Rycote Neoprene Mini-Lavalier Foam Windscreen is a single, water-resistant windscreen designed for miniature lavalier microphone capsules measuring 0.11" (2.8mm) in diameter. The rubber compression collar ensures a snug fit with thin lavaliers such as the Sanken COS11, Sennheiser MKE-1 and Sony ECM-88. Its open-cell foam provides up to 20dB of pop and wind noise suppression without affecting the microphone's transparency. The neoprene-coated, water resistant material keeps the microphone element free of moisture.
