I Received a new C-5, in Sept. From Championhelmets, & also ordered the Sena SC-2 Communications system. I love the helmet,
but the microphone would go in but, does not click into the helmet port on the helmet. I was afraid it would fall out..
So I sent it back to them, (only the SC-2) I'm still waiting to hear back from them, ;-( Has anyone else had the type of problem with the C-5 & SC-2?

Thanks,

Lon McComas
