Keychron S1 vs Lemokey P1: your questions
The Lemokey P1 Pro is the only one with wireless support, offering both Bluetooth 5.1 and 2.4 GHz connectivity alongside a 4000mAh battery. The Keychron S1 is strictly wired, so the P1 Pro is the clear choice if you need a wireless setup.
No, the Keychron S1 is designed for Gateron low profile mechanical switches only, as stated in the product description. For standard MX switch compatibility, the Lemokey P1 Pro supports most 3-pin and 5-pin MX-style switches.
The Lemokey P1 Pro has better sound dampening, as it includes a combination of IXPE, PET, and absorbing foam. The Keychron S1 does not mention any sound dampening features in its specifications.
Yes, the Keychron S1 is available with a hot-swappable option, but it only supports Gateron low profile mechanical switches. The Lemokey P1 Pro is also hot-swappable and supports a wider range of standard MX switches.
The Keychron S1 is more portable, weighing 960g with an ultra-slim low profile design. The Lemokey P1 Pro is significantly heavier at 1650g, making the S1 the better choice for travel.
Yes, both the Keychron S1 and the Lemokey P1 Pro support QMK and VIA for remapping keys. The P1 Pro also supports the Lemokey Launcher web app, which provides an additional method for customization.
The Lemokey P1 Pro is generally better for gaming due to its optional 2.4 GHz wireless with 1000 Hz polling, gasket mount for comfort, and a knob for in-game controls. The S1 is wired with a 1000 Hz polling rate but lacks these features.
The Keychron S1 uses low profile double-shot PBT keycaps, while the Lemokey P1 Pro uses Cherry profile double-shot PBT keycaps. Both are non-shine-through, but the P1 Pro's Cherry profile is taller and standard-sized.
The Keychron S1 has a lower minimum typing angle of 3°, with a second option at 6°. The Lemokey P1 Pro has a fixed typing angle of 5.5°, so the S1 offers more adjustability for a flatter wrist position.
Yes, the Lemokey P1 Pro offers a barebones (DIY kit) version that does not include keycaps or switches, allowing for full customization. The Keychron S1 is only available as a pre-built keyboard.
The Lemokey P1 Pro is designed to be quieter, featuring multiple layers of acoustic foam (IXPE, PET, absorbing foam) to dampen sound. The Keychron S1 does not mention any sound dampening materials, so it is likely louder.
