Tri-mode wireless connectivity and high-capacity battery life

This keyboard features three distinct connection modes to adapt to any workspace layout. The 2.4 GHz wireless option provides a desktop connection with a 1000 Hz polling rate, matching the speed of a wired USB-C connection. For multi-device setups, Bluetooth 5.2 offers a reliable connection with a 125 Hz polling rate, allowing you to pair and switch between up to three devices like laptops, tablets, or phones. Powering these wireless modes is a high-capacity 3750 mAh battery. It delivers up to 300 hours of continuous typing with the RGB backlight turned off, or up to 172 hours when running the RGB backlighting on its lowest brightness setting, reducing the frequency of charging cycles.

Acoustically dampened typing with Keychron Super Red switches

Engineered to minimise hollow case noise, the keyboard features a sophisticated, multi-layered acoustic structure. It integrates IXPE, PET, and EPDM sound-absorbing foams inside its ABS frame, which absorb internal vibrations and dampen the sound of bottom-out keystrokes. This acoustic dampening works in tandem with the linear Keychron Super Red switches, providing a smooth, quiet keypress that is well-suited for shared office spaces and late-night gaming sessions. The solid 1100 g chassis weight ensures the keyboard remains firmly planted on your desk, while the adjustable feet offer dual typing angles of 2.4 degrees and 8.2 degrees to support natural wrist positioning.

Full-size layout with hot-swappable hardware flexibility

The 100% full-size layout includes 108 keys, providing a dedicated number pad, navigation cluster, and function row for maximum productivity in spreadsheets and complex applications. The hot-swappable sockets allow you to easily swap out the Keychron Super Red switches for any other 3-pin or 5-pin MX-style mechanical switches without soldering. For long-term durability, the keyboard is equipped with double-shot PBT keycaps in a comfortable Cherry profile. These keycaps resist oil shine over time and feature shine-through legends that let the customisable RGB backlighting shine clearly in low-light environments. You can choose from 22 different RGB backlight options directly from the keyboard to suit your aesthetic preference.

Open-source QMK customisation and multi-OS compatibility

At the core of the keyboard is an ARM MCU WB32F3G71RCT6 microcontroller with 256KB of flash memory, which provides the processing power needed for advanced key remapping. With full QMK firmware support and the web-based Keychron Launcher software, you can easily remap any key, create custom macros, or set up personalised shortcut layers. The keyboard is fully compatible with Windows, macOS, and Linux operating systems. It supports N-key rollover (NKRO) in both wired and wireless modes, ensuring that every simultaneous keypress is registered accurately, no matter how fast you type.
