The mic I have works across the room, but e.g. our living room is arranged in such a way that sometimes you sit with your back towards where the mic is. In that case, you have to turn around and address the mic, as it were. Also, when you're all the way across the room, you have to speak up - not just talk at conversational level, or mumble under your breath as I tend to do. How well does the Acousticmagic work in such cases? Can you speak away from it, and will it still pick it up? Furthermore, how well does it work wrt background sound filtering? Does it hear you when the tv is on, or when children are playing or similar cases? Those are the main cases in which my setup requires speaking up.
