Keychron K3 Max RGB Brown Switch Wireless Low-Profile Keyboard (Black)
Keychron K3 Max is an ultra-thin 75% layout wireless mechanical keyboard that combines elegance, performance and versatility. With triple connectivity (2.4 GHz, Bluetooth 5.1, wired) and a 1000 Hz readout frequency, it delivers lightning-fast responsiveness, ideal for work and gaming. QMK/VIA support allows full customization, while PBT overlays and IXPE acoustic foam ensure quiet, comfortable typing. Compatibility with macOS, Windows and Linux, Gateron Brown switches, RGB backlighting and an aluminum chassis make the K3 Max a versatile, stylish tool for demanding users.
Full freedom for work and entertainment
The Keychron K3 Max offers maximum versatility with three connection modes. You can enjoy reliable 2.4 GHz wireless connectivity with a lightning-fast 1000 Hz refresh rate for minimal latency - ideal for dynamic gaming and precision work. The keyboard also supports Bluetooth 5.1, allowing simultaneous connection to three devices such as a computer, smartphone and tablet. And if you prefer traditional solutions, the wired mode guarantees stability and even greater responsiveness.
Ultraslim design
Sleekness and elegance are what set the K3 Max apart. Thanks to Gateron's low-profile switches, the keyboard is up to 31% thinner than standard mechanical models. The solid aluminum casing not only emphasizes the modern design, but also ensures durability and stability during daily use. The ergonomic design with three levels of angle adjustment allows you to type comfortably without straining your wrists, even during long hours of work.
Unlimited customization and compatibility
Thanks to the open-source QMK/VIA software, the Keychron K3 Max allows you to fully customize the keyboard to suit your needs. You can easily program macros and shortcuts, as well as assign functions to each key. Support for the hot-swappable mechanism means you can replace any low-profile Gateron mechanical switch in seconds without soldering. The browser-based Keychron Launcher allows you to configure without installing additional software - all you need is an Internet connection. The keyboard works seamlessly with Windows, macOS and Linux. What's more, it has been designed with a Mac layout, retaining the full functionality of the multimedia keys typical of Apple devices. Additional keycaps for both systems are included, so you can quickly switch between platforms.
Security, privacy and performance
Every day you type passwords, contact information and other sensitive information on your keyboard. Keychron K3 Max uses QMK's open source software, which can be verified by the community, ensuring that it contains no hidden features or security vulnerabilities. You have full control over the security of your data. At the heart of the keyboard is a powerful ARM MCU with 256 KB of Flash memory, ensuring reliable operation and lightning-fast responses. With a 1000 Hz polling rate in 2.4 GHz and wired modes, latency is virtually imperceptible - even during intense gameplay.
Typing comfort at the highest level
The low-profile Gateron MX 2.0 Brown switches offer balanced, tactile feedback - ideal for those who prefer to work between linear and clicky characteristics. Dual PBT overlays guarantee a superior typing experience and abrasion resistance. The PBT material is oil-resistant, ensuring that the keys maintain an aesthetically pleasing appearance even after prolonged use. Redesigned stabilizers eliminate the wobble of larger keys such as Space, Shift and Enter, ensuring that every press is smooth and precise.
Thoughtful design - elegant and practical
The Keychron K3 Max is not only about performance, but also about exceptional comfort. The keyboard is equipped with IXPE acoustic foam, which dampens key sounds for quiet operation. The latex foam increases the stability of the switches, improving responsiveness and durability. In addition, the Keychron K3 Max offers more than 22 RGB backlighting modes so you can customize the look of the keyboard to suit your style. You can adjust the color, brightness, saturation and speed of the effects, and if you prefer a more subdued look, a static white backlight option is also available.
