I live on my phone as a network engineer. I have to have clear calls and LOTS of battery life. This headset DELIVERS! It is small enough that I can put it in my pocket on the rare occasions that it is not appropriate (meetings, etc.). It does not get in my way while working. It is light and comfortable to wear. It was easy to pair with my Nokia 6102i. Since I bought this, I rarely use the headset to talk with.
