Jawbone 2 is great.. I have different ear buds then the factory model. They are seperate ones for free from Jawbone that fit just in your ear slighty and you hardly notice them. Check deal a day sites. I got mine from 1saleaday.com for $50.
The BlueAnt Q1 is usually compared to the Jawbone. Both would probably be considered in the ear headsets. Have a look at the Plantronics Voyager Pro which gets really good reviews and goes over the ear. It is a bit bulky for some, but I read that the call quality and noise cancelling are top notch.
