Shure A4PF SM4 Magnetic Microphone Pop Filter

The Shure A4PF is a magnetic pop filter built exclusively for the Shure SM4 microphone. Rather than relying on a separate gooseneck arm or clamp mount, it attaches directly to the SM4 body using integrated magnets, snapping into the correct position every time. This makes setup and removal nearly instantaneous—ideal for podcasters, streamers, and home studio users who want a clean, clutter-free recording setup without sacrificing plosive protection.

Constructed from metal, the A4PF is sturdier and easier to maintain than traditional nylon-mesh pop filters. It intercepts fast-moving air from hard consonants before it reaches the microphone capsule, smoothing out plosive bursts that would otherwise cause distracting low-frequency thumps in recordings. Because Shure designed the filter specifically for the SM4's acoustic characteristics, it preserves the microphone's intended frequency response rather than introducing coloration. The compact, integrated form factor means there's no extra hardware cluttering your desk or mic stand—just a streamlined filter that stays put magnetically and does its job transparently.
