Heil Sound WSM Standard Foam Windscreen for PR20 PR22 PR35

Heil Sound WSM: The Standard Windscreen for PR-Series Handhelds

The Heil Sound WSM is a slip-on foam windscreen made for the PR20, PR22, and PR35 handheld dynamic microphones, molded from open-cell acoustic foam. A windscreen is a porous foam cover that fits over the microphone grille and diffuses fast-moving air before it can strike the diaphragm. For live vocalists, hosts, and instrumentalists using these Heil handhelds, it keeps takes clean without softening the voice.

Sized for the PR20, PR22, and PR35

Rather than a loose universal cover, the WSM is dimensioned to the PR-series handheld grille so it seats snugly and will not slip off in the hand. A correct fit matters because a windscreen that shifts around exposes part of the capsule and lets pops sneak through. Performers moving on stage can grip and gesture with the microphone knowing the screen stays in place take after take.

Plosive and Breath Control

Explosive consonants like B and P shove a concentrated puff of air at the capsule, producing a low thump that muddies the low end of a vocal. The WSM catches and spreads that air burst so the diaphragm never sees the blast, while the open-cell structure keeps highs and intelligibility intact. This lets a singer or presenter work close to the microphone for a warm, present tone without triggering distracting pops.

Wind Rejection on Stage and Outdoors

Air moving across a bare grille, whether from an outdoor breeze or a fast stage entrance, creates a rumble that can swamp a vocal. Fitting the WSM breaks up that airflow and drops wind noise to a level that keeps the voice out front. Live sound engineers and mobile presenters count on that protection when the environment around the microphone cannot be controlled.

Genuine Heil Replacement Foam

Foam covers wear out, compressing and discoloring with regular handling until they no longer shield the capsule properly. This genuine Heil replacement restores the correct fit and acoustic behavior so a PR20, PR22, or PR35 keeps sounding its best. Keeping a spare WSM on hand means a worn or lost windscreen never interrupts a rehearsal, gig, or session.
