Negative Reviews:

Now if it would actually play music

Maybe I got a dud, but after charging the unit, it would not play music from an iPod or an iPhone. The rest of the controls worked on the unit to control the phone or iPod's Pause, Forward, Back, but I could not tell if the volume worked because it never made a sound. And yes the volume was up at 80% on the iPod and iPhone. I will be returning it tomorrow for a new unit because I really like the idea of the product, if it will work.

Great sound, but lacking innovation

I own the predecessor of this speaker set up and have taken it everywhere, really everywhere. Both speaker systems produce awesome quality sound for the size and price. Though I'm glad to see the integrated controls for volume and cell phone, there were other changes made that are obvious steps in the wrong ddirection. Fully integrating the charge and audio cable is a mistake, the wiring is the weakest link in the system, once it wears out the system is useless, perhaps bluetooth connectivity would have been a more beneficial feature that I would have paid extra for, and removeable auxiliary and charging cables.
