All in all, I like this headset.  It is so light that it is easy to forget that it is on my ear.  The ability to charge off the USB port of my computer is also nice; I charge it at work and it is a great arrangement.  The battery life is exceptional; after about a week of draining it completely and recharging it, I haven't had it run out of juice ever.  The first week, it only ran for a few hours before dying:  It should be noted that you should always completely drain and completely recharge a rechargeable-powered device for about the first week to avoid "charge memory" problems.  All in all, a good headset.
