BlueAnt Z9 ROCKS

:D
Fourth try is the charm. Ptronics 520 to 655 to Jawbone to Blueant Z9.

Pros:
Super light and comfy. Could easily wear all day
Easy buttons and set up.
5.5 hrs talk 200 stand by!
REALLY clear and loud on both ends and a DSP that actually works.
Cool Looking.

Cons:
A little pricey (99.00 Best Buy) but you get what you pay for.

Go get one.

Paid $129 last year for mine and love it as well. BEST bluetooth headset out there! Jawbone is just marketing hype IMO...

Another plus for the Z9 is user-upgradeable firmware :D
