Suitable for most microphones-- 48mm/2 inches high, 31mm/1.22 inches connecting thread. These are designed for use with our SM58 Vocal Dynamic Microphone and others like it! Just unscrew the old grille, screw on the new one, and you have a brand new microphone. Good Protector for Microphone Head--The screen grille bears the impact and expels it as screen deformation. These grilles are designed to protect your mic by being recessed when touched, keeping your mic assembly safe! Built-in Foam Windscreen--The new replacement mic grill ball with built-in foam windscreen reduces wind, breathing, popping, and helps absorb moisture so the capsule won't get wet. Meet Your Needs--You will receive 4 SM58 compatible microphone grills, the classic and simple style meets your needs. The price is low enough that it's worth replacing even if it gets dirty, otherwise you'll have to spend time with cleaner and toothbrush. Perfect Replacement-- This anti-sag grill is the perfect replacement for your aging, dented or dented microphone grill. It might not have any effect on the sound, but they definitely make your mic look better.
