Like I said I have been trying to find a headset for year. I've tried Plantronics, Motorola, generic wired headsets and others that I can't remember at this time. The Z9i is perfect for me. It's light and comfortable, so after a while you won't even know that it's there. I have read that the volume buttons are difficult to push (or something like that), but I like it the way it is. It's not too sensitive that you have to adjust the volume every time that you put it on, but not to rigid that you have to use a clamp just to adjust the volume. The voice clarity is clear, even when I had my sunroof open driving down the highway. I can still hear my friend and he could still hear me. The pairing between the Z9i and my Tmobile G1 was very easy, it only took me a minute at most to pair them. There's not much else that I can say about this headset, except I highly recommend it. Although I wouldn't pay full price for it, I got mine for about $60 including s/h, but for those who like paying full (retail) price for everything, I would say that it's money well spent.
