    Unidentified MFG - 4221700372 - Audio. Microphone Grille/Windscreen.

    If you’ve ever spoken into a microphone before, you probably know to speak into the metal grille for the best results. Chanced are you’ve spoken into a handheld microphone with a spherical grille. Microphone grilles come in many shapes and sizes and have many purposes for microphone performance!

    So what is a microphone grille? A microphone grille (or “grill”) is the protective mesh-like layer around a microphone’s capsule. Grilles provide varying degrees of protection from physical trauma, plosive gusts of air, and moisture while still allowing sound to enter the mic capsule effectively.

    The windscreen attenuates wind noise and environment noise and provides ample protection.

    Material: Metal, Heavy Screen.

    Overall Dimensions: 1.714" (43.5mm) Wide x 1.648" (41.8mm) High.

    Threaded ID 1.289" (32.7mm x 5/16").
