AKG W81 White Foam Windscreens for MicroLite Cardioid Lavalier Mics 10-Pack

AKG W81 White Foam Windscreens: A 10-Pack for Cardioid MicroLite Microphones

The AKG W81 white foam 10 pack is a set of ten open-cell foam windscreens for the cardioid MicroLite miniature microphone series, fitted over the wire-mesh protection cap already on the capsule. Ten is the quantity that matches how these parts are consumed, because a windscreen on a hidden body microphone is a per-production and often per-performer item rather than something that lasts the life of the microphone. Each one adds only a minimal amount to the visible size of an already ultra-miniature capsule, which is the entire point of using a purpose-made screen instead of generic foam on a microphone chosen for its invisibility. In white they disappear against light costume, a pale lapel and ceiling-facing install positions.

How Open-Cell Foam Actually Protects a Capsule

Open-cell foam works by turning fast-moving air into slow-moving air before it can reach the diaphragm. Wind noise and plosive pops are not really sound at all but pressure gusts, and a condenser diaphragm cannot tell the difference between a gust and a signal, so it responds to the puff of a hard consonant or a draught from an HVAC diffuser with a low-frequency thump that no console filter fully repairs; a maze of interconnected cells diffuses that airflow across thousands of tiny paths while letting the acoustic wave pass through largely unaltered. That is why a windscreen sized and shaped for a specific capsule matters more than the raw foam, since too dense a layer starts audibly dulling the top end while too thin a layer stops nothing. Sound crews mounting a lavalier at the hairline or on a lapel an inch below the chin get the benefit immediately, because that placement puts the capsule directly in the path of the wearer's own breath.

Fitment: Over the Mesh Cap, and Only on the Cardioid Series

Correct fitment has two parts and both are easy to get wrong. First, these windscreens go over the WM81 cardioid wire-mesh protection cap rather than in place of it, and that distinction matters because the mesh cap is an acoustic component that helps define the cardioid pattern, not simply armour, so removing it to fit foam changes how the microphone hears. Second, this pack serves the cardioid 81-series capsules specifically, covering the LC81 MD lavalier, the EC81 MD ear-hook and the HC81 MD head-worn microphone, while the parallel W82 pack is the correct part for the omnidirectional LC82 MD; mixing the two is the most common ordering error in this accessory line. Users report that the fit over the mesh cap is secure and correct, unlike generic foam that works loose and disappears into a costume mid-scene.

Rotation, Hygiene and Stocking a Room of Presenters

Consumable protection is the workflow this pack is built around, because foam that has absorbed sweat, foundation, hairspray and breath moisture is no longer doing its acoustic job and is no longer something a production wants to hand to the next person wearing that microphone. A presentation coordinator running a conference stage through a dozen speakers in a day can fit a fresh windscreen per talker from a single pack, keeping both the hygiene story and the plosive control intact without pulling microphones out of rotation to dry. Theatre wardrobe and sound crews work the same way between performances and cast changes, house-of-worship technicians replace them on platform microphones that sit near HVAC diffusers or open doors, and rental inventories restock them as a line item alongside the microphones themselves. Buying the ten-pack alongside a MicroLite microphone is what keeps a run, a conference or a rental fleet from stopping over a piece of foam.
