such as IXPE, PET and EPDM, ensuring a superior audio and typing experience.

Significantly improved acoustic foams

Upgrade your typing with the K2 Max featuring advanced IXPE acoustic foam for increased comfort, combined with elastic EPPM foam for superior key switch support, responsiveness and durability. The steel plate provides immediate feedback and a quiet typing sound, while the added weight will enhance stability.

2.4 GHz & Bluetooth connection

Every detail matters for a personalized typing experience, so we give it to you. You can hot-swap every switch on the K2 Max with almost all 3pin and 5pin MX-type mechanical switches on the market (including Cherry, Gateron, Kailh, Panda, etc.) without soldering. You can customize your own typing experience in seconds.

Suitable for All Devices

Designed with the Mac user experience in mind while maintaining compatibility for Windows devices, it features a system switcher and an additional set of custom keys for both Windows and macOS systems.

Program with QMK & Launcher.

QMK open source firmware means endless possibilities for key remapping, macros, shortcuts and more. Now you can easily customize each key with the Keychron Launcher web app.

An epic core inside

A powerful ARM architecture MCU equipped with 256KB Flash will provide more flexibility to developers. The polling rate is 1000Hz in 2.4GHz and wired modes right out of the box, which makes lag barely noticeable even in competitive games.

Keychron Super Switch

Our exclusive Keychron Super switch adopts a new mold with unparalleled precision. Each switch is tested for professional grade quality and has a lifespan of up to 50 million clicks, providing great reliability and high performance for long typing sessions. Its new light-affecting structure in its transparent upper casing also ensures high light transmittance and a more stable, brighter backlight effect.

Screw-in PCB stabilizers

Even a small part matters to the feel of your finger. We've incorporated PCB-mounted screw stabilizers for a smoother typing experience with less wobble on the big keys like spacebar, shift, enter and delete. Keychron K2 Max also supports third-party screw-type PCB stabilizers.

OSA Profile Double-shot PBT keys

To further refine your typing experience, the K2 Max comes with our unique OSA profile (OEM profile with spherical angle) and double-shot PBT keycaps, which aim to provide a more comfortable finger feel with exceptional durability in oils for long-term use in the 75% assembly.

RGB lighting with south orientation

The south-facing RGB is designed to better illuminate the keyboard backlight from the typist's angle. The south-facing RGB is also free from interference when the user installs alternative Cherry profile keycaps on their keyboard. It comes with more than 22 types of RGB backlight settings. You can further adjust RGB hue, saturation, brightness, effect speed with ease.

Ergonomic support

Three levels of adjustable typing angle (50, 90 & 120) and curved OSA profile keycaps work together to provide long-lasting ergonomic support for your wrist.
