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. Includes a 1-year warranty and U.S.-based support. Simply strap and snap the elastic attachment to fasten and securely keep the windscreen on your lavalier mic. Each fuzzy microphone cover is made of artificial fur (a cats favorite toy).
