I'm very satisfied with this headset. It's easy to operate and paired easily with my Treo. Audio quality is acceptable and from the other headsets I've tried, I think it's as good or better than others. I had a problem with the battery not charging after about 8 months. Plantronics sent me a new one and just wanted the old one shipped back in the box. Fast, easy and great product support, just make sure you've got a copy of your purchase receipt.
