How's the positioning of the mic? You running it as it's intended or in the cheek pad?I used the purple panda for a while, but still found it too noisy, I've recently switched to using an Interphone Prosound mic and it's by far the best I have used so far. That said I seem to have partially killed a mic adapter riding in the rain this last weekend. So I'm having other issues now!
However YMMV, there are so many variables - I get a lot of turbulence off the fairing of my bike at certain speeds which causes it's own issues.
