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.
