The Keychron K2 and Logitech MX Keys S represent two distinct keyboard philosophies. The K2 is a compact mechanical keyboard with deep key travel, full RGB, and switch-swap freedom. The MX Keys S is a polished office keyboard with quiet scissor switches, a full-size layout, smart backlight, and productivity software integration. Both offer wireless multi-device switching — but the experience they deliver is fundamentally different.

Keychron K2 — Review
The K2 is Keychron's most popular keyboard for good reason. In a 75% layout that keeps arrow keys and a function row without a numpad, it packs Bluetooth 5.1 multi-device switching, hot-swap sockets, and your choice of switches into a plastic chassis that weighs under a kilogram. The 4mm key travel of mechanical switches — whether you choose tactile Browns, clicky Blues, or smooth Reds — creates a typing experience that laptop-style keyboards simply cannot replicate. Per-key RGB backlighting with customizable effects adds a visual dimension the MX Keys S white-only backlight cannot match. The K2 is not perfect: the tray mount and plastic body produce a higher-pitched sound than premium boards, and the software experience requires some comfort with QMK firmware for advanced remapping.
Pros
- Mechanical switches provide deep key travel (4mm) and tactile feedback that scissor keyboards cannot match
- Full per-key RGB backlighting with extensive customization options
- Hot-swap sockets let you replace switches without soldering
- Longer battery life thanks to a larger capacity battery cell
- More affordable entry point than the MX Keys S for comparable wireless functionality
Cons
- No numpad — 75% layout will frustrate users who rely on number entry
- No smart backlighting — backlight does not automatically activate on approach
- No app-specific key remapping via software (Keychron uses QMK/VIA, not consumer-friendly)
- Louder typing sound may not suit open office environments (depending on switch choice)
Logitech MX Keys S — Review
The MX Keys S is Logitech's flagship typing keyboard for professionals. Its scissor switches with concave spherical keycaps create a fast, accurate typing experience optimized for speed rather than tactile satisfaction. The proximity sensor that automatically illuminates the white backlight as your hands approach is a small but genuinely useful touch. Logi Options+ software unlocks per-application shortcut customization, letting you assign different functions to the same key depending on whether Photoshop, Chrome, or Excel is in focus. Flow integration with a Logitech MX mouse transforms the combination into a multi-computer workstation. The full-size layout with numpad is a practical advantage for finance, accounting, and data roles that the K2's compact 75% layout cannot address.
Pros
- Scissor switches with spherical key caps are quieter and thinner than most mechanical keyboards
- Smart backlight sensor detects hands approaching and illuminates automatically
- Logi Options+ enables per-app shortcut customization, flow between computers, and macro recording
- Multi-device switching works via both Bluetooth and Logitech Unifying USB receiver
- Full-size layout with numpad is essential for accountants, data entry, and spreadsheet-heavy workflows
Cons
- Scissor switches feel shallow at 1.8mm travel — not satisfying for heavy typists or gamers
- Shorter battery life (~10 days with backlight) versus weeks on the K2
- No hot-swap or switch customization — the typing feel is fixed at purchase
- Premium price for a scissor-switch keyboard when mechanical alternatives cost less
Which Should You Buy?

Frequently Asked Questions
Is mechanical or scissor switch better for typing all day?
It is personal preference. Many touch typists prefer the tactile feedback and deeper travel of mechanical switches (like the K2 with Brown switches) for reduced finger fatigue. Others find the lighter, shorter scissor switches of the MX Keys S faster and quieter. Try both if possible before committing.
Can the Keychron K2 connect to multiple devices like the MX Keys S?
Yes. Both connect to up to three devices via Bluetooth 5.1. The MX Keys S adds a Logitech Unifying USB receiver for a fourth connection option, which is useful on older computers or devices with Bluetooth reliability issues.
Which keyboard is better for a Mac setup?
Both work well on Mac. The Keychron K2 includes Mac-specific keycaps and has a toggle switch for Mac/Windows mode. The MX Keys S works seamlessly with macOS via Logi Options+ and has function-key shortcuts that match Mac behavior. The K2 feels more native for Mac power users; the MX Keys S is smoother for multi-OS switching.
Is the MX Keys S good for gaming?
Not particularly. Scissor switches have shorter travel and less tactile feedback than mechanical switches, and the MX Keys S does not have anti-ghosting or gaming-mode features. The Keychron K2 with linear or tactile mechanical switches is the far better gaming option.
Does the Keychron K2 have software for remapping keys?
Yes, but it requires QMK or VIA firmware flashing — not as beginner-friendly as Logi Options+. If you want simple drag-and-drop key remapping with a GUI, the MX Keys S and Logi Options+ is the easier solution.
Which keyboard is quieter in an office?
The MX Keys S is significantly quieter. Its scissor switches produce a muted click similar to a laptop keyboard. The Keychron K2 can be made quieter with silent switches (e.g., Gateron Silent Red or Banana), but even silent mechanical switches are generally louder than scissors.
Does the MX Keys S work with Logitech Flow?
Yes. With Logi Options+ and a compatible Logitech mouse (like the MX Master 3S), you can use Flow to seamlessly move the cursor between two computers and copy-paste between them — one of the most useful productivity features Logitech offers.
