This is my second BlueTooth headset, after a Jabra, and is a definite improvement. Crystal clear sound, good range and is very comfortable to wear. Has quite stellar sound cancellation too.I am not a big fan of devices which stick in your ear canal and the Voyager uses a different approach with various size foam pads that rest against the opening in your ear, but not in it.Other reviewers have made comment about the size of the power button. Yes, it is small and odd-shaped, but who cares? It's easy enough to use unless you have very odd shaped hands and no thumb.Now to the issue of battery life. Plantronics claim days, other users have reported hours of life. I believe I have figured out why this occurs. I use this headset with a Nokia 6600 and found that if you terminate the call with the phone instead of the headset, the headset remains connected to the phone via BlueTooth, draining the battery even when not on a call. If you terminate a call with the button on the headset, it will break the BlueTooth connection with the phone (after a couple of minutes) and you will get the days of battery life Plantronics claim. To remake the connection, you have to press the button on the side of the headset - the connection may take several seconds to hook up. Not sure if this is a bug with the BlueTooth protocol, the phone, or the headset. Personally, I have found that BlueTooth is not a very well implemented protocol by most manufacturers.In summary, well worth buying, especially at the bargain prices it is currently being offered at.
