"I have had 3 pairs sent to me, each set malfunctioned."1.0 starson by cashclub
Pros: Sounds good when it was working.
Cons: After one or two uses, some of the features stopped working. Eventually the unit simply would not turn on or reset. I got a replacement from Plantronics but it only lasted a couple of weeks. I got a 3rd replacement and it went bad too.
Summary: Great concept, poor quality. Don't waste any money or time on the backbeat 903 or 906. I finally asked for a different product from Plantronics. I hope the Voyager Pro that they are sending will at least function for more than a few weeks.
