The microphones of camcorders and also external microphones are particulary touchy against wind low frequency noise, which occurs especially with wind noises. Wind noises contain very large portions of these low frequencies. With the use of our Windshield, Windscreens those wind noises can be nearly completly eliminated, without effecting the rest of the frequency spectrum. Our Windshield, Windscreens are available in different sizes fit for your camcorder or microphone model. Designed in Germany.
