WindTech 300 Series Windscreen 35 mm
The WindTech 300 Series Windscreen fits microphones with a 35 mm inside diameter. It is built for outdoor photographers and videographers who need clean audio when recording in windy conditions. The brown finish gives a professional look that matches existing gear.
Thermals noise and power draw
This passive foam accessory has no electronics, so it produces no heat, no fan noise and draws no power. The open-cell SonicFoam construction lets sound pass freely while reducing wind velocity at the capsule. It also shields the microphone from dust and dampness during extended outdoor use.
Deciding specification
The critical specification is the 35 mm inside diameter, which must match the microphone body exactly. If the microphone is larger or smaller, the windscreen will not seal properly and wind protection will fail. Buyers who need a different diameter should look for another size.

Questions about this item
How do I install the 35 mm windscreen on my microphone?
Stretch the open-cell SonicFoam over the microphone head until the 1.375 inch inside diameter seats fully; the step often missed is pushing it past the grille ridge so wind cannot leak underneath.
When will the brown #309 windscreen need replacement?
Replace the foam when it shows permanent compression, crumbling cells, or discolouration that cannot be brushed off; open-cell acoustical foam degrades with UV and moisture exposure over time.
What limits wind-noise reduction during a long shoot in steady gusts?
The 300 Series foam reduces wind velocity but cannot block turbulence that exceeds the material’s pore-structure capacity, so sustained high wind will eventually leak low-frequency rumble.
