The differences between the Logitech MX Keys S and the Logitech MX Keys for Business are not immediately apparent, as they share many similar features. However, here are a few points to consider:

- Connection technology: Both keyboards use wireless technology, but the MX Keys for Business is specifically designed to work with the Logi Bolt receiver, which offers enhanced security and reliability in congested wireless environments.
- Design features: Although both keyboards have similar designs, the MX Keys for Business is often associated with business environments and can include additional features to enhance productivity.
- Customisation options: Both keyboards can be customised via the Logi Options+ application, but the MX Keys S may offer more options for backlighting and battery management.

If you don't see any visual differences, it could be due to the similarity of their designs.
