A Fit That Stays Put The biggest frustration with replacement filters is when they sag or look sloppy. Our solution includes a custom-molded retainer ring. Once installed, it locks the foam in place for a secure, factory-style fit that won't budge even if you move your boom arm constantly. Professional Grade Audio This isn't just a colorful sponge. We selected a specific density of open-cell foam that allows air to pass through naturally. It effectively kills plosives and breath blasts while preserving the "broadcast" warmth that makes the SM7B famous. Your audience will hear your voice exactly as it should be—clear, crisp, and distraction-free. Built for the Camera If you're on video, your gear is part of your brand. Choose a color that stands out or complements your RGB setup. It's an easy, low-cost way to make your content look more unique and professional. Installation Tip: The foam might arrive slightly compressed from shipping. Just pop it out of the bag and let it sit for a few hours (or give it a quick splash of water and air dry), and it will return to its perfect round shape.
