On-Stage ASWS58-B Foam Windscreen for Handheld Ball-Grille Microphones (Black)

On-Stage ASWS58-B Foam Windscreen: Protect the Capsule, Tame the Plosives

The On-Stage ASWS58-B is the working live-sound windscreen for handheld ball-grille microphones in the SM58-size form factor. It stretches over the grille of any standard handheld dynamic microphone (Telefunken M80 family, Shure-class handhelds, Sennheiser e835/e845, Audix OM-series, Audio-Technica AE-series) and stays in place through aggressive hand-held vocal performance. The foam is acoustically transparent — no high-frequency loss through the screen — and the construction reduces wind, plosives, and breath transients without compromising the microphone's sound.

What the Windscreen Actually Does in a Live Mix

The visible function of a windscreen is wind blockage. The audible function is plosive reduction. P, B, and T consonants in close-mic vocal performance push a burst of air at the capsule — that air burst hits the diaphragm and produces a low-frequency thump that the front-of-house engineer either filters with a high-pass EQ or hears as a distracting punch in the mix. The ASWS58-B's acoustically transparent foam diffuses that air burst before it reaches the capsule. The result: cleaner vocal recording, less corrective EQ in the live mix, and a more professional sound on the PA.

Fit and Hold on Standard Ball-Grille Microphones

The ASWS58-B is sized to stretch over a standard ball-grille handheld microphone — the SM58 reference form factor that Telefunken M80, Sennheiser e835, Audix OM-2, Audio-Technica AE6100, and dozens of other professional handhelds share. The foam stretches to a snug fit that does not slip during energetic stage performance. Multiple buyer reviews confirm the fit stays put through aggressive hand-held vocal work, drops, and repeated stretching cycles across multiple gigs.

Outdoor Stage and Festival Use

The primary outdoor use case is wind blockage — a handheld microphone on a windy outdoor festival stage picks up gusts as low-frequency rumble that the PA mix engineer cannot remove without aggressive high-pass filtering. The ASWS58-B's foam blocks most wind energy before it reaches the capsule, reducing the rumble at the source. Outdoor weddings, festivals, parade reviewing stands, and political-rally microphones all benefit from a foam windscreen as standard equipment.

Cleanliness and Capsule Protection

House-of-worship microphones, conference handhelds, and karaoke equipment share an unspoken problem: multiple users sharing the same microphone over time deposit dust, dried saliva, and stage moisture on the capsule grille. Over time that buildup degrades the microphone's sound and creates a hygiene concern. The ASWS58-B sits between the user and the capsule — it is the visible cleanliness barrier that takes the wear instead of the grille. When the foam shows wear, it gets replaced for a few dollars; the microphone underneath stays clean.

Color-Coding Multiple Vocalists

The ASWS58 family ships in multiple colors — black, red, blue, green, orange, pink, yellow, and gray. Stage management uses the colors to identify which vocalist is on which microphone at a glance: the lead vocalist on the black-foam mic, the backing vocalist on the blue, the drum stand handheld on the red. The visual color-coding makes setup, line-check, and troubleshooting faster on a multi-mic stage.

Who This Windscreen Is For

Live vocalists performing on handheld dynamic microphones who want cleaner plosive performance on the PA. Outdoor wedding and festival vocalists where wind is the primary noise source. Houses of worship using handheld microphones across multiple vocalists and speakers per service. Conference and corporate-event vocalists where multiple speakers share a single handheld microphone over the course of a session. Stage managers running multi-vocalist stages who use color-coded foam to identify microphones at a glance.
