Do a search and you will a few threads re: the Jawbone. Many people who tried the jawbone with the Q found it to be a quality headset, however they also found that the Q seemd to have some BT quirks exhibited in connection with the Jawbone.
I have a Jawbone that I used with a Samsung i730 before getting the Q9m, and I love my Jawbone. I have found that in connection with the Q9m, it has been a good headset (no BT quirkiness), althought the volume is a little lower than when I use it with my Samsung.
I have to say that the Jawbone works great in my convertible to cut down background noise. However, wind-noise is a problem with the Jawbone (just like any headset w/o a windsock). But in my car, wind is often not the problem, but passing trucks and other background noise is, and the Jawbone works great in this situation.
Hope this helps.
