Best so far! Better than Jawbone!

Don't listen to the previous reviewer.

When I lost my silver Jawbone, I was bummed out for a day or two. Then I had to get another headset due to my work requirement. I thought to myself that I had got to get another Jawbone for sure.

But I did a little research, then decided to give BlueAnt Z9 a try (I had 30 days, holiday trial period to return). To my surprise, Z9 performed much better than my lost Jawbone.

The the incoming sound is so much clearer. First test, I could hear every word and the little movement my best buddy made along with his cell phone, i.e, he was carrying his grocery (on one hand) to his apartment while talking to me on his cell phone (on the other hand). The outgoing sound to him was surprisingly clear to him, I was driving during this whole conversation, and he thought I was at home.

(I had spoken to him while driving with Jawbone before, He could heard stuff in the background and didn't sound at all as good as Z9 according to him.)

Did more test, same positive result.
