Microphone Blimps, or Mic Zeppelin as they are sometimes called, are windscreens that surround microphones with the purpose of reducing wind noise when recording audio at outdoor locations. Essentially a hollow cage with an acoustic cover, they create a volume of still air that surrounds the microphone. An elastic microphone suspension system further isolates the mic from the cage. Refinements to our BMP40R make it ideal for outdoor use for Audio Recordings, ENG, Film and Video production.
