I don't what the other reviewer is expecting from his headset. I am using it with my treo 650 and love every asspect of it. Very long stand by time, very long talk time, and connects to my treo every time without a hassle.The sound quality is great and stable. I used it in a convertible and was able to keep a dissent conversation. As far as trying to to connect with my cell phone from 2 miles away... it was not designed for that ;)
