Product Description:
Genius SP-i200U is a slim, portable USB speaker with a foldable stand for mobile professionals. Two specially designed full-range neodymium micro drivers inside the aluminum cones deliver pure, digital sound better than general laptop speakers. Installation is easy; just plug and play your favorite songs, watch a movie, or make a private multimedia presentation. No power supply is required with the USB-powered connector. It's easy to carry; the integrated cord-wrap cable fits in the body and a pouch is included for your travels.

Rating : - Expected more volume
Maximum volume was lower than that from the internal computer speakers. I am returning it, and will look for a powered set with subwoofer. We have headphones for the notebook that produce enough volume to fry your brain. I expected a lot more based on all the reviews that said the sound was "amazing."
