I bought this little set of speakers to take on holiday with us and to play my ipod nano (new version) on the move.
So far, I have been quite impressed. The nano docks well in the docking slot. The sound is clear and pretty good for such a little thing. It would never do for a party, but in a small room, it can put out a respectable sound!
The USB cable, which is included, works fine and bypasses the batteries if you have them loaded. I have not yet tried a mains DC adaptor.
When the ipod is docked and connected to the computer via the USB cable, it does not sync with the computer or charge, just powers the speakers.
I have read that when docked and plugged to DC power, it will charge the ipod too, but I have not yet tried this.
The only little problem my husband had was that when he had the ipod docked, he could not reach the play button - big fingers - but I can push it with little effort.
Fantastic little product for the price.
(must admit I bought mine elsewhere slightly cheaper than Amazon, but felt so impressed, I wanted to leave a comment on here!)
