Summary: This is a great speaker. perfect for a shelf or on a desk, not in the sight of your boss. A great item from Sony. Only problem we had, is that check before you buy! We have the Sony doking station, and it offers the "Partying " function. The light bulb went off and we thought this speaker and the docking station would work well to distribute music in a large room. WRONG!! It works only through a computer for dual listening. Enjoyable, but not what we purchased it for.
