Trying to find a Bluetooth gaming headset
I've been searching for a good bluetooth headset to replace my wired one. I was looking for something comfortable to wear for hours at a time, etc... and then I read about bluetooth profiles on wikipedia. From what I understand, all bluetooth devices must support one or more "profiles". These profiles dictate what the device can do. This is apparently to keep all bluetooth devices working happily together, and so you don't have to go download new drivers every time you get a new headset for your phone or whatever.
Anyway! It seems that the bottom line, for now, is that there are only two profiles that might be useful for gaming. One, A2DP, allows for high-quality stereo audio to be transmitted from a source (mp3 player, phone, etc) to your headset. This is good, but when in this profile, the headset cannot transmit audio from its microphone. This profile would essentially give me wireless headphones, but I would not be able to talk to teammates in TF2 or what have you. There are two other profiles, which seem essentially the same from what I can see on wikipedia: headset and hands-free modes. They allow for transmission of one lower-quality mono channel to the headset, and voice from the headset to your device. So I could talk to teammates in TF2, but my audio quality would be crappy and mono. To be able to replace my current wired headset, I would need a bluetooth headset that had both high quality stereo audio and voice transmission. Since this profile does not seem to exist, is it safe to assume that there will be no bluetooth devices with the capabilities I'm looking for any time in the near future?
I've been thinking of ways to get around this. I suppose that I could just set a wired mic on my desk when I'm gaming and use the bluetooth headset in A2DP mode for stereo audio. I'd rather not though - seems to defeat the purpose of having a wireless headset in the first place.
One last question: where does bluetooth get its audio from if it's connected to my computer? I have an Audigy, so ideally it would do all the audio processing work, then somehow pass the output to a usb bluetooth dongle. I'm not sure if this is how bluetooth works, however. I suspect that it acts as a separate "sound card" which would not only make my CPU do all the work, but I'd miss out on my Audigy's effects and whatnot. I've seen bluetooth adapters that plug into a stereo output and then transmit to a bluetooth headset. This would let me get my Audigy's proper output, since as far as my computer would be concerned, it would just be talking to a set of speakers. However, I'd rather avoid this since then I would have to get a separate usb bluetooth dongle for my PC to be able to talk to any other Bluetooth devices. And I'd still have to get a wired mic for my desk.
