I purchased this item from a big box store and was very disappointed in the sound quality. Distortion from the minute that it was hooked up. Obviously I had a defective unit, maybe a nondefective unit would have been acceptable at the time. I was not willing to take a chance on a replacement, so I did some research and purchased the Zvox Mini. Blows all the made for ipod speakers out of the water. Sure, I will have to buy a dock to charge my ipod...but I have QUALITY sound...not the hollow and tinny sounding music I have heard from other units. Cannot say enough about the Zvox...check it out-zvoxaudio.com.......many published reviews included on their website.
