If you're a female, or if you have long hair, you might want to think twice about purchasing this headset.  I bought it because it is small and light, but the hook goes on your ear is not designed to work with long hair.  My headset pops out easily, just a 2-3 minutes after I put on, it gradually moves upward because my long hair gets in the way.  So, you can imagine how painful it is to fuss with it, and trying to make it stay, so I can talk for a few minutes.  After trying to put up with it for a week, I gave up.  I am looking at other bluetooth headset that works with my Razer and my long hair. :-)
