I've had quite a number of bluetooth headsets and this one ranks among the 2 I would consider the best. Well built and easy to use this headset performs extremely well with great sound and a good range. I had a Jawbone which I also enjoyed but the attachment for the ear broke...it's a very poor design. The only thing better with the Jawbone was it's noise cancellation which was excellent and better than any other on the market. However, to use the ear attachment on the Jawbone without losing the attachment I needed to super glue it to the headset so when the attachment broke I had to replace the headset. Many people also had this problem with the Jawbone. Hey, the Sony unit is half the price of the Jawbone and for most folks would provide the most important needs for bluetooth headset users. The Sony also comes with a neck strap to hold the headset when you're not using it. It's a big plus and don't understand why other headset mgfgers haven't offered this as a regular standard. Who wants a bluetooth stuck in their ear all the time? I've had alot of people compliment me on that aspect of its design. Try it, you'll like it. Connection was a breeze. I currently use with a Treo 650, which I'm planning on replacing.
