I tried all the obvious fixes - mixing & matching all the external cables, connecting it to the passenger's socket, etc., but when it doesn't work, it doesn't respond to any of these (my wife's identical set works perfectly, though). Moving the boom mike around sometimes causes it to work again, for a few minutes. When I take the helmet apart (moving the mike's wires in the process), it often starts working again, but when put back together...it doesn't. Just wiggling the tiny, hair-thin wire a millimeter or two causes it to work, & not work.
I looked at J&M's site. I considered sending it back & trying for a replacement, but the two-way cost of shipping (I'm in Canada) is virtually the same as buying a new complete set. Interestingly, the cost of a replacement microphone, alone, is MORE than the cost of an entire set (their microphones list from $90-$160USD - with shipping, taxes, brokerage fees, duty, etc., that comes in at around the $200-$300CDN range).



Has anyone found an "alternate" (aftermarket) manufacturer of J&M-compatible headset parts? Surely, there has GOT to be a cheaper way...
