I have used this jabra headset for a couple of years, well since they came out. They work really well with bluetooth phones, and you can buy the one with the dongle that connects to non-bluetooth phones, but I find that a bit cumbersome.

As for the bluetooth phone integration, I think the connection with the Sonyericsson phones I have it is very good, and the sound quality is very good on my end, and on the the called party end.

The only thing I will say is, it does NOT work well in an outdoor environment. If there is a lot external noise, or if you have the windows down, your called party will have a hard time hearing you.

So, the microphone is good for picking up your voice, but it picks up quite a bit else. So, be prepared for that.

Otherwise, the early adoptor in me, and technophile is pretty happy.

btw, the jabra customer service is really tops. Turn around on a defective one was free, and took two days. NQA

Let me know if you are looking for a better deal on one, I have some links
