The Shure A4PF pop filter is designed for vocalists using an SM4 microphone looking to improve their home recordings. Its low-profile, detachable pop filter attaches magnetically to the SM4 shockmount, cutting down undesired plosive "pop" sounds without obscuring your performance. You'll capture pristine vocal takes thanks to the pop filter mirroring the SM4's curve and filtering out bursts of air. Compatible with the Shure SM4 microphone, this pop filter gives you a portable, all-in-one solution for professional-quality recordings.
