I did speak with Blueant tech support today. The fellow was not bullish on modifying the stereo system to mono. He said that a connector to permit the conversion had been brought up, but nothing had been done to forward this notion. He also put forward Bill's theory that the ear pieces are not really in contact with the ears in the case of a motorcycle helmet; I don't have recent motorcycle experience, but I would think the helmet to be pretty snug in that area. Anyway, my plan remains the same; namely, go stereo if I have to. For all I know there is a balance control and, frankly, my left ear hearing ain't all that good anyway. My stoker and I both use mirrors which is really more reliable than sound since overtaking cars can be seen before they are heard.
