The Movo WS10M is a Furry windscreen for portable recorders or microphones for home, studio, and location use. Fits most lavalier microphones 8-13mm and can slip over a foam wind muff providing increased wind protection. The furry exterior minimizes wind blasts and turns it into a low-frequency hum vs. thunderous pop, perfect when filming in a blustering environment or a moving vehicle. Simply strap and snap the elastic attachment to fasten and securely keep the windscreen on your lavalier mic.
