In your first post you said "Couldn't get a clear voice with all the wind noise in the background. She only got 75% of my voice ,and I could not understand her, unless she put her hand in front of the mike."
To me it sounds like wind noise was affecting your ability to use the system. If you have a less than ideal helmet it will affect the quality of your conversation. The fact she could shield the mic and then you could hear her indicates she was reducing the background wind noise by covering the mic.
Maybe someone else can explain it better if he doesn't get this explanation because now I'm confused by his last post.
