Pros: Works exactly as advertised.

Cons: None.

Overall Review: I've now got three monitors set up using a single Radeon 5850 card. I've read reviews saying that you absolutely must get one of those $100+ active adapters that plug into the wall outlet to get that set-up to work, so I was a little scared that this was too good to be true. But it works as advertised, and I'm now sporting three monitors.

Pros: * Good (though not great) audio quality, both outgoing and incoming. * Comfortable fit. * Noise cancellation works very well. * Comes (semi-)pre-charged, so that you can plug it in and go immediately upon opening the box. * Voice commands work well, even in noisy environment (haven't tested in windy environment). * The firmware is upgradeable, so as they fix things and come out with new features, you can get those. * There is caller ID, or as good as it can get on a headset — it reads out to you the digits of the number that's calling.

Cons: * The firmware updating software isn’t yet compatible with 64-bit flavors of Windows (December 2009). * After going out of Bluetooth range for more than a few seconds, it won’t automatically re-connect when you’re back in range (you have to restart the phone). This might have been fixed in newer firmware. * Whenever any audio stream cuts off, it says “call disconnected.” This also happens when, for instance, you’re listening to a voice mail on an iPhone, and the voice mail ends. * Charges via proprietary connector, instead of mini-USB.

Overall Review: There are 2 killer features of this headset: voice commands, and voice isolation technology. The voice commands work great for me. I've read other reviews that say that they don't work well, but the only problem I ever had was when I said the wrong command -- if you say "battery status" instead of "check battery," it will misinterpret and do something that you didn't mean for it to. But if you're ever unsure, just say, "What can I say?" and it will list the voice commands you can use. The voice commands even worked like a charm with the stereo blasting loud in my face. The voice isolation technology on this phone works at least as well as that of the Jawbone. It actually works better for me -- I could never get the little nub on the Jawbone 2 to stay touching my face, and every time it lost contact I was essentially put on mute. Not a problem with the Q1. At O'Hare airport, my friend said it was like I walked into a quiet room when I activated the voice isolation max mode.
