The Rycote Mini Windjammer is a lined slip-on fur cover designed for use with the Zoom H4, Nagra Ares-M digital recorder. This windshield provides 30 dB of noise reduction from the effects of high-wind and gust noise and vocal plosives.
The Mini Windjammer can be used over a foam windscreen or on its own. A touch-fastener strap secures the windjammer in place.
Bought this for the H4 because the wind screen was super weak and fell off my mic when I was recording an event. Works exactly as it claims, the only bummer is that it covers up the record button when it's on the device. but it can easily be pushed up to reveal the buttons. Overall solid though.
I'm using this Windjammer on an original H4. It's great in moderate wind conditions and it was able to handle the wind generated by the Washington DC Metro subway. The only thing I don't like is how the Windjammer is secured to the recorder. To make it tight enough the velcro strap overlaps onto the furry part. You also have to be careful not to mount the Windjammer too low since it can get in the way of the jog wheel.
