The Pop Blocker with 12" Flexible Gooseneck & Replacement Liners from On-Stage is a 6"-diameter micro-weave nylon filter that prevents annoying vocal thrusts, breath sounds, and plosives while recording. The 12" flexible gooseneck allows for precise positioning of the Pop Blocker between you and your mic, and a durable V-Bar Clamp easily attaches to shafts with up to 0.9" diameter. In addition, two 6"-diameter micro-weave filters are included.
