Not sure why the exclusive, but I can guarantee you this product rocks. It's super high quality, fits like a charm and feels really good & solid when I'm wearing it.
The holder/carrying stand/case is the best feature to come with a Bluetooth headset I've ever seen. It keeps it charged, provides a nice cradle/carrying case for the ear piece when not in use. I've never seen the Voyager Edge anywhere else besides Best Buy. It may be that they were the only retailer to carry that specific model for a certain period of time. I haven't seen one on the shelf at my local store for over 6 months.
