I have the [ame="http://www.youtube.com/watch?v=CZR26HHSs4g"]motorola oasis[/ame] and wear it all the time. Most of the time I don't realize I'm wearing it and have even climbed into the shower a couple of times not realizing I had it on. I had the plantronics voyager for a couple of years but the neck broke and I just couldn't get super glue to hold any longer. I was very happy with it though I often found myself looking for it at home when my phone rang. The oasis disconnects when you remove it from your ear.
I need the behind the ear type as I never found the on ear type comfortable or would it stay in place.
