The ASFSS6-GB Dual-Screen Pop Blocker is a pop filter that removes unwanted "P" and "B" plosives by providing open space between the two screens. The first screen diffuses the air burst that causes plosive consonants; the open space between the screens disperses air pressure; and the second screen diffuses the air again and removes remaining plosive sounds. The 11.5" gooseneck is constructed from coated brass and allows for precise positioning of the Pop Blocker between you and your mic.
