I just bought the Cardo Scala 500 for my Treo 650 (Sprint) and love it so far. I was able to get the silver version. It cam with a headset, holster, lanyard, charger, glasses adaptor and a car charger for the Scala 500 which was a big welcome surprise. Pairing was simple and volume and sound are very good. Not a bad deal for $35.00 shipped. So far, I recommend.
