First the negative: Occasionally it fails to pair with my Nokia phone, the phone sees the headset but the headset won't communicate with the phone, requiring both to be reset. It is also slightly bulky behind the ear and could be more comfortable with glasses.On the bright side, the battery life is great, the voice dialing works a treat, and the controls are trivial to master. The range is easily 30' from the phone and it retrains automatically. I use the phone in traffic, usually with the windows or top down and it is easy to hear and be heard with this unit. With its great design, it doesn't move at all and there is no danger of it falling or being knocked off.If you're looking for cute, look elsewhere; if you want an affordable and reliable headset, this deserves a close look.Update 18 months later: I've gotten to the point I don't notice the unit behind my ear but it is still noticeable when I'm wearing glasses. Recently, I started riding motorcycles again and the headset not only works, but stays in place when I'm riding. If you wear a helmet that fits properly, you'll never get it on over the Plantronics but, if you ride dangerously, this is the unit to use.It only gets better with age.
