This tailor-made windblocker was especially created for CEECOACH and works very well with our Jabra Chill Headset (also usable with other stereo headsets). Wind noise is evidently minimized when training outside. With a little hook & loop tape the windmuff is fastended securely around the mic.
The windmuff is not water-resistent. In case you experience heavy rain and it gets soaked, please unfasten the windmuff and let it try (if required wipe the mic with a try cloth).
