These are perfect for my Soundman OKMs and I'm very impressed with the quality of these windshields. I haven't recorded using them in a storm yet (though I definitely want to!) but they have been fantastic at stopping light and medium wind noise. Aurally, they are very transparent and I haven't noticed any colouration on the recordings; I tend to wear them even if there's a slight chance of wind or if I want to keep my ears warm! They also help keep my Soundman OKMs in place and have a good fit so I don't need to worry about pulling out the mics by accident or the windshields pressing against the mics, etc. I would certainly recommend anyone with a pair of Soundman OKMs (or any other binaural in-ear mics for that matter) gets a pair of these.
