Compare Keychron C1 vs C3 Pro Differences Side by Side

This comparison is for buyers looking at two similar wired 80% keyboards from Keychron: the C1 and the C3 Pro.

Pros and Trade-offs

If you value a quieter typing experience and want to fully program your keyboard with custom layers and macros, the Keychron C3 Pro's gasket mount and QMK/VIA support make it the clear winner. However, if portability, a lighter weight, and a choice of backlight colors are more important to you, the C1 is a capable and well-reviewed alternative. Both keyboards offer hot-swap capabilities and a familiar TKL layout, so your final decision should hinge on whether you prioritize customization or simplicity.

Keychron C1

+Lighter weight (685g) making it more portable than the C3 Pro.
+Available with RGB, white, or non-backlight versions, offering more backlight variety.
+Includes 12 multimedia keys for quick access to controls.
+Over 180 customer reviews with a 4.8/5 average rating, showing strong user satisfaction.

−ABS keycaps may wear down faster than PBT alternatives (the C3 Pro includes PBT/ABS options).

Keychron C3 Pro

+Gasket-mount structure with sound-absorbing and case foam for a quieter, smoother typing experience.

+Pre-lubed Keychron Mechanical switches (non-clicky) ensure a smooth feel out of the box.
+Three adjustable typing angles (4°, 6°, 8.7°) for ergonomic customization.

−Heavier at 912g, making it less travel-friendly than the C1.
−Red backlight only, offering no RGB or white backlight options.
−Only 2 customer reviews available, so long-term reliability data is limited.
−VIA keymap JSON file must be manually loaded since it is not yet automatically recognized.
