Finally I found a bluetooth earpiece for my cellphone that works in my YJ softtop. It's a Jawbone Prime. I was on the interstate last night doing 65 with the left upper door window partially down and was able to hold a normal conversation on the phone. In fact my wife asked my why I was yelling and it was because I thought I had to over the road noise and roof flapping.
In case you didn't know the Jawbone has noise/wind cancelling.
