Rating : - Great sound, moves around desk
These USB-powered speakers showed up right away on my MacBook. They sound great, but the stand design makes them move around the desk when played loud. I compared these with the V10 notebook speakers, and decided that to keep the V10 speakers, because they are easier to travel with. If you plan to stay in one place, and don't mind moving these back or taping them down, these are nice speakers.
