Those are cool, but I prefer the Motorola S9. Lightweight, synchs with almost everything (even iPods), decent battery life, and if you can get past the Geordie LaForge similarity, looks pretty cool. The cons however, can be dealbreakers depending on how you use it. It's water-RESISTANT, not waterproof. So if you sweat profusely and wear it every day, as in while working out, after a few months to a year, the buttons will short out and stop working--until they dry out that is, when they'll instantaneously start working again all by themselves. Another con is the I-can't-hear-you microphone. That may just be a problem with my particular headset, but it's really annoying. Thankfully, my BlackBerry can be set to automatically route calls to the phone, even when I'm listening to music on the headset. When the call ends, it automatically switches back to the headset and your music.

Overall, I love my S9, since I rarely use my phone for phone conversations, and I've learned to live with the once-a-year short-outs. I just use a wired headest for a week until the S9 dries out.
