The SWS-250 Furry Windshield Cover was designed to fit the SGM-250, SGM-250P, SGM-3416 and SGM-3500 microphones to provide maximum protection against wind noise in windy outdoor environments while remaining acoustically transparent. This cover is made to slip over the microphone's included foam windscreen. This windshield will not fit the SGM-250CX; instead use SWS-CX.
