Summary: Great headset... when it works. This headset has the best noise isolation, but these things don't last very long. That's why you see so many broken ones for parts for sale, or refurbished ones that have an even shorter life and sometimes pairing problems. I have a drawer full of dead ones, so they're not worth replacing unless you can get them for cheap.
Summary: My fifth Jawbone Headset. Was much happier with the Original ICON, and with ERA. The New ICON HD has a very short Battery Life and it usually runs out by mid-afternoon, even with moderate usage. The Original ICON lasted for a full day, the ERA even longer. This new HD is usually just Half of a day and needs a re-charge.
