I have a Zephyr 550 that has been sitting around without much use.It's a bluetooth audio speaker/speakerphone and mobile charger all in one.
More info here: http://www.spar.com/zephyr-550.html
Original retail is about 150.
Does not come with original box. Comes with the unit, a 3.5mm cable, and USB + charger.
There is a mark on one of the sides (unit came like this new).
70$ shipped US.
