After some initial doubts as to whether such a favorable Popscreen really good for what I was taught from the first shots better. At our Neumann TLM 67 (currently still 1,400 on the market), we were able to achieve great results. No measurable attenuation across all frequencies, for perfect elimination of all air Ströh stoves, tiled-dependent noise. The two-layer version of Memebran is solid. The gooseneck stable and remains in the desired position. All around a very good product - and significantly better than nylon stockings over hangers (which then would not really cheap).
