What's wrong with the description?
- They're stereo speakers (2.0, not 2.1).
- The don't have a "3.5mm jack audio input".
- They aren't working with "any computer setup", they're only compatible with certain Mac models with a special plug (PowerMac G4 Cube and iMac G4).
- They don't support THX or Dolby Digital. In fact, they don't support any digital signal at all.
