Description

Introducing the Keychron K3 Max QMK/VIA Wireless 75% Custom Brown Switch Mechanical Keyboard. An ultra-slim, highly customisable mechanical keyboard designed for users who want premium performance, flexible connectivity, and a refined typing experience. Featuring a compact 75% layout with 84 keys, the K3 Max maintains essential functionality while offering a space-saving design that is ideal for modern workstations and gaming setups. With support for 2.4GHz wireless, Bluetooth 5.1, and USB Type-C wired connections, this keyboard provides the versatility needed for seamless use across desktops, laptops, and multiple operating systems.

Designed for productivity and gaming, the Keychron K3 Max delivers fast and responsive performance with a 1000Hz polling rate in both 2.4GHz wireless and wired modes, helping minimise input delay for accurate and immediate keystrokes. Equipped with Gateron Low Profile Brown switches, the keyboard provides a tactile typing experience with a satisfying feedback response and medium sound level, making it well suited for office work, programming, gaming, and extended typing sessions. The hot-swappable design allows users to replace switches easily without soldering, giving enthusiasts the freedom to customise their preferred typing feel. Powered by QMK/VIA firmware, the K3 Max offers advanced customisation options through the Keychron Launcher web app, allowing users to remap keys, create macros, and configure personalised shortcuts. The powerful ARM Cortex-M4 32-bit MCU with 256KB Flash memory ensures stable and efficient operation, while built-in IXPE acoustic foam helps reduce typing noise for a more comfortable experience. Redesigned stabilisers improve consistency and reduce unwanted movement on larger keys such as the Space Bar, Shift, Enter, and Backspace. For Apple users, the dedicated macOS layout provides familiar function keys and an intuitive transition from traditional Mac keyboards.

Combining durability, style, and long-lasting wireless performance, the Keychron K3 Max features low-profile double-shot PBT keycaps that resist oil buildup and maintain their premium appearance over time. The keyboard includes 22 RGB backlight effects plus a white backlight option, allowing users to customise lighting brightness, colour, and speed to match their setup. Its 1550mAh rechargeable battery provides up to 73 hours of wireless use with the backlight disabled and up to 42 hours with RGB lighting at low brightness. With its slim design, tactile mechanical switches, advanced customisation features, and multi-device connectivity, the Keychron K3 Max is an excellent choice for professionals, gamers, and keyboard enthusiasts seeking a powerful low-profile mechanical keyboard.
