Logitech MX Keys S vs Keychron K2 comes down to two very different approaches to everyday typing. The MX Keys S is a full-size, low-profile keyboard designed around quiet productivity, while the Keychron K2 is a compact 75% mechanical keyboard with hot-swappable switches and a more customizable typing experience.
If you want a quiet keyboard with a familiar full-size layout and easy multi-device switching, the MX Keys S is the more straightforward choice. If you prefer mechanical switches, a smaller footprint, and the ability to change switches later, the Keychron K2 is the better fit.

Key Differences Between the MX Keys S and Keychron K2
The biggest difference is not a single specification. It is the way each keyboard is designed to be used.
Logitech MX Keys S
Quiet · Full-size · Productivity
Keychron K2 Version 2
Mechanical · Compact · Customizable
The MX Keys S focuses on a quiet, familiar typing experience, a full-size layout, and productivity features. Its low-profile design makes it a natural fit for office and productivity setups.
The Keychron K2 takes a more compact and mechanical approach. Its 75% layout removes the number pad while keeping the function row and commonly used navigation keys. Its hot-swappable Gateron G Pro switches also give you the option to change the typing feel later.
1. Typing Experience: Low-Profile vs Mechanical
This is where personal preference matters most.
Logitech MX Keys S
- Quiet
- Low-profile
- Best for shorter travel
Keychron K2 Version 2
- More tactile
- Mechanical
- More key feedback
The MX Keys S uses Logitech’s low-profile scissor-style keys, designed for a quiet and consistent typing experience. Its low-profile design also gives it a feel that is familiar to many laptop users.
The K2 Version 2 uses Gateron G Pro mechanical switches and is available with different switch options. Because the switches are hot-swappable, compatible switches can be changed without soldering.

2. Layout and Desk Space: Full-Size vs 75%
The two keyboards take very different approaches to desk space.

Full Size · With Numpad
Keychron K2 Version 2
75% · No Numpad
- Need a numpad? → MX Keys S
- Need more desk space? → K2
3. Wireless & Multi-Device Use
Both keyboards are designed for wireless use, but they take different approaches.

Device 1 · Device 2 · Device 3
Keychron K2 Version 2
Bluetooth + USB-C
↓
Wireless · Wired
The MX Keys S supports Bluetooth and Logitech’s Logi Bolt receiver, and Logitech allows it to switch between up to 3 connected devices.
The Keychron K2 Version 2 uses Bluetooth 5.1 and can connect to up to 3 devices. It also supports a wired USB-C connection when you want to use it without Bluetooth.
If you frequently move between a work laptop, personal computer, and tablet, both can work well.
4. Features: What Do You Actually Get?
| Feature | Logitech MX Keys S | Keychron K2 Version 2 |
|---|---|---|
| Backlighting | Smart backlighting | Adjustable backlighting, depending on configuration |
| Multi-device switching | Up to 3 devices | Up to 3 Bluetooth devices |
| Productivity software | Logi Options+ | — |
| Mechanical switches | — | Gateron G Pro |
| Hot-swappable | — | √ |
| Number pad | √ | — |
| USB-C | Charging | Wired connection + charging |
| Mac / Windows support | √ | √ |
The important difference is the approach. Logitech focuses more on productivity software and workflow features, while Keychron gives more attention to mechanical typing and switch customization.
5. Battery Life and Charging
Logitech MX Keys S
Up to 10 days
Backlight on / predefined settings
Keychron K2 Version 2
Up to 240 hours
Backlight off, standard version
The MX Keys S can run for up to 10 days with backlighting on, according to Logitech, with longer battery life available when backlighting is turned off.
The Keychron K2 Version 2 uses a 4000mAh rechargeable battery and is rated for up to 240 hours of typing with the backlight off. Actual battery life varies with backlight use and other settings.
For either keyboard, battery life depends on how you use the keyboard and how often the backlight is active.
Best for: Both offer enough battery capacity for regular desk use, but the K2’s 240-hour figure assumes the backlight is off.
