The PS04 is a studio-grade microphone pop filter with a dual-layer 4.75-inch nylon mesh screen and a 5.25-inch overall diameter. It reduces pops, plosives and sibilance while protecting the microphone from saliva. It attaches to standard mic stand shafts or booms with the included C-clamp and enables precise positioning via an 8-inch gooseneck, with a 1-inch maximum grip. Durable construction for studio use.
