Ok I have got me one of these and with just one day of use I have to say the Jawbone has the best sound clarity going. I still don't know how to use everything correctly I am still experimenting.
Forum factor, the size is a little on the large side of most bluetooth devices. It comes with several accessories to make the fit more custom to you, it has 2 sizes of ear hooks, small and large, has separate hooks for left and right. If you like to change ears during the day you will need to carry an extra ear hook with you to change. There are 3 different ear peaces available. I am using the round ear peace and the large right ear hook. The Jawbone is light and comfortable on my ear and I was able to keep it on for several hours at a time. I wear glasses so ear hooks that rest on the lower ear cause problems with my glasses, but this ear hook seams to sit high on the era lobe and doesn't interfere with my glasses like some others do. It takes a while to get used to putting the Jawbone on the ear, you have to slide the hook over the ear like putting on glasses you cant just drop it on and this caused me to miss a couple of calls because I didn't get the thing on my ear quickly enough. With a little practice I got it figured out.
Using the Jawbone, the answer button is cleverly hidden behind the flat surface of the main body so it is easy to get to. There is a button to turn of the noise shield, I think this is there just to show off the quality of the sound, you get 6 hrs of talk time with the noise shield on so why would you turn it off. The callers I tested on tell me they can hear me without any problem even while driving with the windows rolled down. The Jawbone has no buttons just for volume the noise shield button is used to adjust the sound level there are 6 levels and each touch of the noise shield button takes you to the next level. As the background noise rises the jawbone has auto volume that will adjust the ear peace sound so the volume steps are just to set the base level. The reaction time of the auto volume is a little slow and I would miss a few words as the auto volume would come up but I am still testing this and I could be doing something wrong.
Conclusion, I like it so far, remember after only one day, I would recommend to anyone who needs to talk in loud areas this is the device for you. This is a must have for me, I am never in the office and conduction business while working or in loud areas is an every day thing for me. The best thing for me is I don't have to yell to get the caller to hear me. I hate when I know other people are able to listen to my conversations, with the jawbone I can just wispier while I am talking and the caller can hear me. I am very happy with the Jawbone and despite the high price, $119 is what I payed, I would recommend this Bluetooth device.
