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-inch gooseneck is constructed from coated brass and allows for precise positioning of the Pop Blocker between you and your mic.
