Have you used it in a convertible?
Nevermind -- found your thread on it.

Thanks! Good to hear test results of this type with both of these headsets. Most people neglect to consider what it sounds like to callers on the other end and only focus on fit and audio quality on their end.

Cost is an absolutely worthless indicator of performance. I recall spending nearly $100 on the Moto HS810 and finding it to perform worse than the Plantronics M3500 that only cost about $30 at the time. Granted, the M3500 is a bulky and really old model that I wouldn't recommend today (there are far better options these days).
When comparing you really have to test them out or at least start with reviews where others have actually tested them.
