The 0.9" diameter Baseball Windscreen and Baseball Windjammer Combo Kit from Rycote includes a Baseball felt-covered windscreen and a Baseball windjammer. The kit is designed to fit over a shotgun or similarly shaped microphone to greatly reduce unwanted noise swooshes during fast swings and other rapid boompole movements. It is lightweight and offers increased performance over conventional foam windscreens.
The Baseball is built with open-cell foam and covered in a felt material. It can be used for fast/deep booming and plosive reduction. Additionally, it helps protect your mic.
In addition, the Baseball windjammer is made from synthetic fur especially sourced and constructed to provide maximum wind protection and audio transparency. It is designed to absorb the impact of the wind, so it doesn't reach your microphone. The performance of the Baseball Windscreen with the Windjammer fitted is -40 dB wind-noise attenuation across the frequency spectrum.
