    BE-010 Microphone Windscreens

    On stage or in a recording studio, a microphone is the most important device you need to capture vocals and instruments. Whether you're cutting your hit single or rocking out in front of a large crowd, your microphone projects everything you do, so having good quality mic accessories just makes sense. Windscreens and grilles are small, lightweight and portable components that can really impact the sound of your performance. Windscreen and grilles are covers that improve the sound quality of a microphone. Normally a windscreen is made from foam and a grille from metal. They act as a filter to prevent popping, breath sound, moisture and wind noise from reaching your mic.

    Dimensions: 1-5/8" tall with a 7/16" Diameter Opening and an Inside Depth 1-1/3"

    High Quality Multi Foam is ideal for reducing wind, sibilance and pop noise.

    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.
