Companies like Genius always try to make their speakers, and other products, stand out through good looks, not just audio quality, which is why the SP-U115 turned out the way they did.
The main difference between them and other speakers is that they are connected to PCs (desktops and laptops alike) via a USB+audio jack combo, rather than normal audio jacks.
Spec-wise, they have 2-inch driver units, which is sufficient for home entertainment and better than laptop integrated speakers.
The signal-to-noise ratio is decent as well: 80 dB, which suggests a higher clarity too.
The volume can be controlled via a small dial on the side of the right satellite.
To buy the Genius SP-U115 USB speakers, assuming one lives in Canada or the US, a payment of $14.99 / 14.99 Euro will be necessary. One out of four front color options can be selected.
