I wasn't sure whether this should go in the technical area or the Roadster area, but since this is a common issue with Roadsters (and other convertibles), I chose to put it here. - I hope that is OK.

I'm sure many of you have gotten sick of trying different earpieces that either don't let you hear the other end, or even worse, the person on the other end of the call can't hear you when you have the top down. I've tried literally a dozen different kinds of earpieces and finally found one that really works. The Shure Quietspot really works well. The downside - it is wired, and doesn't have a turbo button, but it works!!! Only $39.95 at Buy.com!
