Update:
Bought said Jabra tonite at Best Buy. Haven't got a chance to use it in a conversation yet, but just messing with it, and this thing is cool as shit. Called my voice mail with it, and the sound is pretty damn clear.
Volume controls don't seem to do anything though. Not sure what that's all about.
Oh, and voice dialing through the headset FTW. I thought I'd still have to pull out my phone to make an out-going call, but that's not the case. Tap the call button, say who you want to call, tell it 'yes' to confirm, and away you go.
I really should have picked one of these up sooner.
