Microphone Windscreens are vital to most aerobics instructor's headset microphones (except the Aeromic and Cyclemic) to achieve maximum audio quality and durability. Each headset microphone's capsule has a specific shape and most manufacturers make a specific windscreen for each microphone. Oval-shaped models are designed to fit the E-mic from Fitness Audio and Samson's QE model. Shure and Audio-Technica headset microphones usually use a round or spherical design. These can all be hand-washed or rinsed. You'll also find temple-pads for Audio-Technica headsets here.
