The 60 level device is tremulously quiet in the wind relative to other products, but the 90 level is virtually wind noise free. Wind does not actually have any sound, but when it hits another object it creates a turbulence, which is what we know as wind noise. We were able create this noise across our microphone and the 16 band equalizer allowed us to write an algorithm that all but cancels the turbulence. In short, there is virtually no wind noise in our 90 level technology.
