The new Jawbone Bluetooth headset is smaller and sexier than its predecessor. But I felt like a klutz while initially trying to learn how to use the buttons on it.
After getting over the initial awkwardness of using the hidden buttons and trying to decipher the meaning of the beeps... I'd say its a good Bluetooth headset. It does a great job at eliminating background noise -- you just have to remember to turn on the NoiseAssassin setting. Having the NoiseAssassin off only makes sense if you're in a really quiet area.
I thought the ear hook would be an issue for me because it wasn't a tight fit around my ear. But it turned out not to be a big deal because it stayed in place throughout hours of gabbing. And I'm very animated when I gab.
