Listen to the verdict
Want mechanical feel and programmability? Keychron K2 Pro. Want silence, slim profile, and Logi Flow across devices? MX Keys S.
These solve different problems despite the similar price. The K2 Pro is for typing enthusiasts who want a satisfying clack and full programmability. The MX Keys S is for office workers who want a productivity tool that's invisible to colleagues and integrates with the Logitech ecosystem (MX Master 3S mouse, Logi Flow).
Both clips below are the manufacturers’ own product videos — marketing by the two parties this page compares, not independent evidence. The verdict here is ours.

If you type 4+ hours a day and the act of pressing keys matters to you, the K2 Pro is on a different level. Pick the switch (Brown for office, Red for gaming, Blue if your colleagues can't hear you) and the typing feels deliberate, tactile, and satisfying in a way membrane keyboards just can't match. The hot-swap sockets mean you can change the feel later without buying a new keyboard.
The full QMK/VIA programmability is a sleeper feature. You can define layers (one tap of a key = letter, hold = modifier), remap Caps Lock to Escape, set up macros, and persist these across machines because they live in the keyboard's firmware, not your OS.
In a shared office, on calls, in a quiet cafe — the noise difference is the deal-breaker. The MX Keys S is barely audible from 2 metres away; the K2 Pro is unmistakably mechanical from across a room. If you take 3+ video calls a day, your microphone will pick up every K2 Pro keystroke.
Logi Flow is the other unsung feature. If you also use a Logitech mouse (MX Master 3S), Flow lets you move your cursor from a Mac to a Windows machine to a Linux box seamlessly, with shared clipboard. That's an entire KVM switch replaced by a software feature.
| If you... | Choose |
|---|---|
| Type 4+ hours a day and notice the feel | Keychron K2 Pro |
| Take video calls and don't want mic noise | Logitech MX Keys S |
| Want to customise everything (layers, macros) | Keychron K2 Pro |
| Use 2+ computers and want Logi Flow | Logitech MX Keys S |
| Work in a shared office | Logitech MX Keys S |
| Code or write fiction | Keychron K2 Pro |
| Need a numpad daily (finance, data entry) | Logitech MX Keys S (full-size) |
| Hate charging things every week | Logitech MX Keys S (5-month battery) |
| Prefer aluminium build over plastic | Keychron K2 Pro |
Buy the Keychron K2 Pro if typing feel matters to you and your environment can absorb the noise — home office, dedicated studio, gaming setup.
Buy the Logitech MX Keys S if you work in a shared space, take calls, or value the Logitech ecosystem (Flow, Options+, the MX Master 3S as a companion mouse). For most office-bound knowledge workers, this is the right answer.
