I have a bose qc3 with a bluetooth kit. Pretty expensive and it's not really wireless. There's a wire from the headset to the bluetooth kit. Even though it has noise cancelling, it doesn't filter the noise for a outgoing voice so you will hear the background noise when Im talking.
The jawbone II is a killer. You can host a conference call in a restaurant without anyone realizing it. The jawbone original is good also, just a little bit bigger. It has been reported that in some cases it's better than the jawbone II.
