Bought this for my wife for Christmas. I gave it to her today and this thing is awesome. Easy to set up which is what I worried about the most. Great sound, and does exactly what it's supposed to do. Pretty cool little chunk of technology. ~ Amazon Review
Inside it has a little wall wart not micro USB but it is a 21 watt adapter that's 15 volts at 1.4 amps which is why it can't be USB, it has a little over one meter cord you also get some documentation and things that you can ask the a-word again gonna try to keep that to a minimum. You have your power input and aux output on the back which looks to be a three-and-a-half millimeter plug and on top you've got your plus and minus volume buttons your mute button as well as the action button and all the flower-filled microphones built in with an LED ring light around.
