Keychron C3 Pro
Tray Mount TKL Comparison
- Gasket mount design for a potentially softer, more cushioned typing feel.
- North-facing RGB with shine-through, Cherry-profile PBT keycaps for bright legends.
- Vendor description specifies pre-lubed switches and a 3.5mm EVA acoustic foam layer.
- North-facing RGB can cause interference with Cherry-profile keycaps.
- Uses plate-mounted stabilizers, which are typically harder to tune than screw-in.
- Slightly heavier and larger dimensions than the C1 Pro.
Your choice depends on your priority for typing feel versus modding potential. Select the Keychron C3 Pro if you want a softer, potentially more acoustic typing experience out of the box with its gasket mount and pre-lubed switches. Choose the Keychron C1 Pro if you plan to modify your keyboard extensively, valuing its screw-in stabilizers and south-facing RGB that guarantees compatibility with aftermarket Cherry-profile keycaps.

What will you mostly use it for?
The keyboards tie in most scenarios due to their shared high-end wired features. The C3 Pro has a slight edge for content creation due to its gasket mount and shine-through keycaps. The C1 Pro is the better choice for modders, specifically because of its screw-in stabilizers and south-facing RGB that avoids keycap interference. For gaming, office work, programming, and travel, the core experience is virtually identical.
It's a tie
- Both offer an 8000Hz adjustable polling rate for low latency.
- Both feature N-Key Rollover for simultaneous key presses.
- Both are wired-only, ensuring a stable connection.

“My son loves it. Upgrade from an implosion cap version. Not used to the US layout but he it learning some python. Might as well use a US Keyboard”
“Looks great and sounds amazing but keys gets stuck/don’t work or double press too often. When I remove the key caps to clean, it still doesn’t fix the problem. Example, my 7 key doesn’t work when pressed and my G key when pressed wrotes two g’s instead of one.”

Keychron C1 Pro vs C3 Pro: your questions
The core difference is the mounting style. The C1 Pro uses a tray mount design with screw-in stabilizers, while the C3 Pro uses a gasket mount design. The C3 Pro also features north-facing RGB with shine-through keycaps, whereas the C1 Pro has south-facing RGB with non-shine-through caps.
The C3 Pro is marketed for its acoustics, with a vendor description highlighting pre-lubed switches, 3.5mm EVA foam, IXPE film, and a silicone pad. The C1 Pro also has sound-dampening foam, but the C3 Pro's gasket mount typically contributes to a softer, more consistent sound profile.
Yes, both the Keychron C1 Pro and C3 Pro have full support for QMK and VIA firmware. This allows for extensive key remapping, macro programming, and customization through the Keychron Launcher web app.
You can physically install them on both. However, the C1 Pro with its south-facing RGB will have no interference with Cherry-profile keycaps. The C3 Pro's north-facing RGB may cause the keycaps to hit the LED housing on certain rows, potentially affecting the feel.
Both keyboards come with Keychron Super switches. According to vendor listings, options include Keychron Super Red (linear), Super Brown (tactile), and Super Banana (tactile) switches. Both are hot-swappable for easy replacement.
Both keyboards feature an adjustable polling rate up to 8000 Hz, which can be set to 1000 Hz or other steps via software. This high polling rate is designed for low-latency input in gaming and fast typing.
Yes, both use PBT keycaps. The C1 Pro uses OSA-profile, double-shot, non-shine-through PBT keycaps. The C3 Pro uses Cherry-profile, double-shot, shine-through PBT keycaps for its RGB version.
The C1 Pro might be slightly more straightforward for stabilizer mods due to its screw-in stabilizers, which are easier to remove and replace without desoldering. Both are hot-swappable, making switch changes equally easy for beginners.
Yes, both the Keychron C1 Pro and C3 Pro are compatible with macOS and Windows. They include a system toggle key (FN + Caps Lock) and extra keycaps for the Mac modifier keys.
Based on the vendor spec sheets, both keyboards include a Type-C to Type-C cable and a Type-A to Type-C adapter. They do not include a switch puller or keycap puller in the listed specifications, so you may need to purchase those separately.
There is a discrepancy. The metadata lists the C3 Pro's weight as 912g, but its vendor spec sheet lists 830 ± 10g. The C1 Pro's weight is consistently listed as 830g. The C3 Pro may be slightly heavier in practice.
