Mechanical keyboard Keychron K8 Max 80% (87 keys) Wired USB + RF Wireless + Bluetooth, RGB, Black

Keychron K8 Max is a wireless custom mechanical keyboard with an 80% tenkeyless layout that supports 2.4 GHz, Bluetooth 5.1, and wired connections. It is configurable via QMK firmware and the Keychron Launcher web app, and includes keycaps for both macOS and Windows. The keyboard features enhanced acoustic foams, a steel plate, and a high-performance ARM MCU with 256 KB flash for flexible customization and low latency.

Advantages

The K8 Max provides multiple connection modes (2.4 GHz, Bluetooth and USB) with a 1000 Hz polling rate on 2.4 GHz and wired modes for minimal latency. Programmability through QMK and the Keychron Launcher enables remapping, macros and separate keymaps for Mac and Windows. Upgraded internal foams (IXPE, PET, EPDM) together with a steel plate and added weight improve typing acoustics and stability. The keyboard ships with OSA-profile double-shot PBT keycaps and hot-swappable support for Keychron Super mechanical switches on the hot-swap version, while screw-in PCB stabilizers reduce wobble on large keys. South-facing RGB backlighting offers broad illumination and compatibility with Cherry-profile alternative keycaps.

How to use

Connect the keyboard via USB for wired use or pair it with a computer, phone or tablet using Bluetooth 5.1 (up to three devices). For competitive gaming or lowest latency, use the 2.4 GHz wireless receiver which operates at a 1000 Hz polling rate. Install the Keychron Launcher web app or use QMK tools to customize keymaps, program macros and configure separate layouts for macOS and Windows. If you have the hot-swap version, remove and install Keychron Super switches without soldering. Replace keycaps using the included macOS or Windows sets as needed.

Recommendations

Use the 2.4 GHz connection or USB wired mode for applications requiring minimal latency (gaming or real-time input). When switching operating systems frequently, keep both macOS and Windows keycap sets accessible and configure distinct keymaps in Keychron Launcher. For improved sound and stability, ensure foam layers and the metal plate remain properly seated; consider screw-in stabilizers and compatible third-party parts for further refinement.
