Best in class Bluetooth headset

This is my latest in a seemingly endless search for the perfect Bluetooth headset.
In a nutshell: Clear and loud sound, effective blocking of background sound, small and light, long battery life.
I am very impressed with this headset, after 6 weeks of daily use.
While bargain headsets abound, there is always a compromise with them, resulting in a lot of people assuming that bluetooth is not ready yet. When you upgrade to this premium headset you'll realize that you can finally have a reliable cordless headset.
I tried this Plantronics 655 with 2 cell phones: Cingular 2125 and Samsung D807 with the same reliable results.
The headset itself looks good and is very light. I found that the optional (included) ear hook was necessary for a secure fit, but I imagine that varies by ear shape.
The package includes 3 sizes of ear tips, an ear hook, a charging cradle, a USB cable, and car cigarette lighter charger.
Shop around, you can find prices about half its list price.
