The Rycote Mini Windjammer is a lined slip-on fur cover designed for use with the Sony PCM D50 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.
Reduced wind noise as effectively as the one that came with the Sony PCM D50.
I don't know of another commercial product that is better than this one. (Surprisingly, it is only slightly better than the ripsop nylon one I made, and if I had known that, I would have stayed with my DIY version.) It fits well, and I have no complaints other than Rycote's high price. Although it greatly reduces wind noise, don't expect it (or any other product) to eliminate noise.
