This is my first prototype of a foam “hollow in the middle” windscreen. I like the Schoeps B5d “hollow” windscreen, but wanted a simmular windscreen for the MKH50/40. With the addition of the windscreen to my kit I am no longer limited to my Cinela Leonard or just the standard foam windscreen. One of the most difficult parts to source was a plastic sleeve that would not scratch the microphone's finish. Now for some testing.
