The purple, ASWS58-P Foam Windscreen for Handheld Microphones from On-Stage is sized to fit over most handheld microphones with a round grille. It helps to reduce undesirable vocal pops, sibilance as well as breath and wind noise.
The ASWS58-P is made of flexible foam material that stretches over the mic for a snug, reliable fit, protecting the mic from moisture and dust.
The purple color helps keep track of your mics.
