“I previously had a normal K4 and i love the new one, the only thing is that the stabilizers lube work is kinda bad and the space bar was very rattly but after some lube work the K4 pro retakes the perfect productivity keyboard.”

Keychron C2 Pro vs K4 Pro: your questions
The Keychron C2 Pro is better suited for competitive FPS gaming. It features an adjustable 8000Hz polling rate for potentially lower input latency compared to the K4 Pro's 1000Hz. Its wired-only connection also provides a consistently stable link without the risk of wireless interference.
Yes, the Keychron K4 Pro supports both Bluetooth wireless and a reliable USB Type-C wired connection. You can use it in wired mode for tasks like gaming, programming via QMK/VIA, or simply to charge its 4000mAh battery.
Yes, both the C2 Pro and K4 Pro feature hot-swappable sockets that support both 3-pin and 5-pin MX-style mechanical switches. This allows you to change switches easily without soldering.
The Keychron K4 Pro is more portable. It has a more compact 96% layout with a length of 391mm, compared to the C2 Pro's full-size 436mm length. Furthermore, its wireless capability eliminates the need to manage a cable while on the go.
The C2 Pro comes with OSA profile double-shot PBT keycaps. The K4 Pro's specifications list both ABS and PBT as keycap materials, suggesting the included keycaps may vary by configuration, with some versions potentially shipping with ABS keycaps.
Yes, both keyboards fully support open-source QMK and VIA firmware. This allows for deep customization, including key remapping, creating macros, and setting up layers through the Keychron Launcher web app or VIA software.
The C2 Pro uses a standard full-size (100%) layout with a dedicated number pad and full navigation cluster. The K4 Pro uses a 96% layout, which condenses the number pad and navigation keys into a more compact block to save desk space while keeping most keys.
The K4 Pro incorporates a steel plate, which can provide a firmer, more resonant typing feel compared to the C2 Pro's plastic plate. Both keyboards feature sound-absorbing foam and silicone dampening pads, and screw-in stabilizers for a solid construction.
Both keyboards are fully compatible with macOS and Windows systems. Each includes keycaps for both operating systems and has a system toggle switch to change key functions between Mac and Windows layouts.
Yes, the Keychron K4 Pro is available in a barebone kit version. This kit includes the case, PCB, plate, and stabilizers, allowing you to install your own choice of switches and keycaps, which can be a cost-effective option for modders.
The C2 Pro offers three adjustable typing angles: 4.8°, 7.8°, and 10.2°. The K4 Pro also offers three angles: 3°, 7°, and 10°. The C2 Pro provides a slightly steeper maximum angle, which some users may prefer for ergonomics.
Yes, both the Keychron C2 Pro and K4 Pro feature south-facing RGB LEDs. This orientation helps prevent interference with Cherry-profile keycaps and provides better backlighting from the typist's perspective, especially with non-shine-through keycaps.
