I am constantly on the road, and with new laws about talking on the cell phone and driving being developed seemingly everyday, I have become very accustomed to using Bluetooth earpieces. I had one previously which I got very cheaply, and was a little small and uncomfortable to wear; however this one while being a good bit larger is not excessively so, and is very comfortable to wear. I had mine on all day and hardly noticed it. The sound quality is also excellent. The only drawback that I have found is that the buttons and indicator light are a little confusing. The call button essentially does everything, however while turning it off I have accidentally made multiple calls today. Overall it is a great product, it just takes a little getting used to after my previous one.
