    Anyone have it yet?

    Supposedly the same as 640 but with DSP for noise cancellation. Seems like reduced battery life, though. Supposed to be available towards the end of March.

    Have one on order! Tried 640 but my wife consistently complains about background noise and asks me to switch to the phone directly when I call her from an airport terminal, which is usually where I call from! Everything else about the 640 is fine, just can't use it! Ha!

    It looks like Plantronics delay the release of the Plantronics 645 until mid April.
