Bought Endwar, have a Motorola H500 Bluetooth Headset. I have downloaded the latest patch for the game. H500 connected without a hitch. Started the game and completed the voice recognition calibration - definitely not seamless! Some commands would not work no matter how I spoke. I'm using the English version. (I live in Australia, don't know whether my accent makes it hard for the software to learn my voice). Numbers seem the greatest problem, especially one (1). The headset is definitely working. I have tried using it located on my ear, and speaking directly into it. No luck. During the game it is hit and miss at best. Even tried putting on a fake American accent, and getting my wife to try calibrating the voice recognition - still no luck!
