These grills are designed to fit SM58 dynamic microphones for vocals and other similar microphones. Simply unscrew the old grill and screw on the new one to give your microphone a fresh, like-new appearance. The metal screen grills absorb impact through controlled deformation, helping to protect your microphone by denting upon contact and shielding internal components. Each replacement grille features a built-in foam windscreen that helps reduce wind noise, breath pops, and unwanted sounds, while also absorbing moisture to keep the microphone capsule dry. This package includes 4 black microphone grille balls in a classic, simple design. The affordable price makes it convenient to replace them when dirty, avoiding the need for deep cleaning with brushes or other tools. This durable grille is an ideal replacement for worn, damaged, or dented microphone grilles. While it may not alter sound performance, it significantly improves the microphone's appearance.
