The Logitech MX Keys and Logitech MX Keys S are premium full-size wireless keyboards designed for office productivity, multi-device workflows, and comfortable typing. While the original MX Keys is still an excellent choice, the MX Keys S brings smarter backlighting, modern wireless options, improved software features, and better customization — making it the superior pick for most users.
Choose the Logitech MX Keys S — it offers smarter illumination, better wireless connectivity (Logi Bolt included), enhanced customization via Logi Options+, and a refined typing experience that makes daily work smoother and more efficient.
Why Do I Recommend Logitech MX Keys S?
- Smart Backlighting That Adapts: The MX Keys S features smart backlighting that automatically adjusts to ambient light and detects your hands as they approach, providing illumination only when you need it — saving battery and improving usability in low-light conditions.
- Modern Wireless With Logi Bolt Included: While the original MX Keys can connect via Bluetooth or Logitech’s older Unifying receiver, the MX Keys S adds Logi Bolt USB-C wireless (included in the box) for a more reliable, secure connection — especially in crowded wireless environments.
- Advanced Customization With Logi Options+: The MX Keys S supports advanced software features via Logi Options+, letting you reassign function keys, create Smart Actions, and tailor workflow shortcuts to apps like Photoshop, Word, or Excel — ideal for productivity.
- Ergonomic, Quiet, and Comfortable Typing: Both keyboards share the acclaimed low-profile scissor switches and concave keycaps that provide a smooth, quiet typing feel suited for long sessions, but the MX Keys S refines the typing experience with updated illumination and firmware.
