After reading reviews, buying headsets and being dissapointed, I finally found a good one. The Voyager 510 is light, and sits securely in your ear. I have checked with many people and nobody has been able to tell I was on a wireless headset so far. Volume is good and it looks ok as well.It is hard to turn on and off. You pretty much have to take it off to do this because the button is so tiny, but the button to answer/make calls is easy to get to and in a good location. So far it has had good battery life. I charge it overnight and wear it for 8-10 hours each day. I highly recommend it.
