Pros and Trade-offs

If you value a slim, lightweight keyboard for frequent travel or a unique low profile typing experience, the Keychron S1 is your pick. However, for most users, the Lemokey P1 Pro is the better investment due to its modern gasket mount, extensive wireless options, quieter sound profile, and modding-friendly features. The P1 Pro offers a more comfortable and versatile daily driver, while the S1 excels in its niche as a portable low profile option.

Keychron S1

+Ultra-slim all-metal design with a full CNC aluminum body, making it highly portable.
+Low profile Gateron switches and PBT keycaps provide a unique, low-travel typing feel.
+Two adjustable typing angles (3° and 6°) for ergonomic customization.
+Hot-swappable PCB compatible with Gateron low profile mechanical switches for easy customization.

−Wired-only connectivity, limiting flexibility for travel and desk setup.
−Limited hot-swap compatibility, as the PCB only supports Gateron low profile mechanical switches.
−North-facing RGB LEDs are less effective with the included non-shine-through keycaps.
−Uses plate-mounted stabilizers, which may be less stable than screw-in alternatives.

Keychron Lemokey P1

+Available in wireless version (P1 Pro) with Bluetooth and 2.4 GHz connectivity alongside a large 4000mAh battery.
+Gasket mount design combined with premium acoustic foams (IXPE, PET, absorbing foam) for a dampened, satisfying sound.
+Screw-in PCB stabilizers provide a stable and rattle-free experience on larger keys.
+South-facing RGB LEDs offer better illumination with non-shine-through keycaps from the user's perspective.

−Heavier (1650g for P1 Pro) and larger than the S1, making it less ideal for travel.
−Higher front profile (19.22mm without keycaps) compared to ultra-slim low profile keyboards.
−The knob and macro column may add unnecessary bulk for users who prefer minimalist layouts.
