These are inexpensive, low-power portable speakers. They will not rock a room or rattle any windows. However, they sound much, MUCH better than built-in laptop speakers and function perfectly for listening to music while at work. Pulling power via USB...

Very satisfied with value and performance. DFD

I had to replace an old set of computer speakers. The price is right for darned good speakers. I wish the wires were a bit longer, though.

Sound was tinny. Cables were inadequate.

I bought 1 that came with a broken speakerI brought another while my 5.50 return charge was in prosses AND IT CAME BROKEN TO. Watchout for the solo speaker. the one with controls I haven't had trouble with. They sound cheap because they are.
