Incorporating the world's first hot-swappable low profile Optical switches to customize per-key typing experience with ease, together with all signature Keychron features.
WIRELESS AND WIRED
Connects via Bluetooth and switch among them easily. Featuring Bluetooth 5.1 chipset, the K3 offers flawless connectivity whether you're working at home or the office while connecting with your smartphone, laptop and iPad.
ULTRA-SLIM
The redesigned low profile switch is 40% slimmer than conventional switches. Together with the streamlined aluminum body makes the K3 one of the thinnest and lightweight wireless mechanical keyboards in the world.
75% LAYOUT
Crafted for productivity, the K3's 75% layout is a compact version of tenkeyless layout. It allows users access to all the essential multimedia and function keys, but with a smaller footprint.
ERGONOMIC ANGLE DESIGN
Two level adjustable rubber feet makes the new K3 more comfortable to type on.
SUITABLE FOR ALL DEVICES
Compatible for both macOS and Windows. Keychron is one of only a few in the market that comes with a Mac multimedia keys layout for Mac enthusiasts (Check high-res keycap layout and size here). For Linux users, we also have a dedicated user group to help with the experience.
HOT-SWAPPABLE
We all have our unique typing preferences, that's why we went the extra mile to make the K3 the world's first hot-swappable low profile Optical switch keyboard. We've implemented a MX-styled stem and stabilizers, and conducted numerous design iterations of the keyboard structure.
You can easily hot-swap every Optical switch in a few seconds to customize your typing experience on the K3 without soldering.
Optical Switch
With the MX-styled stem housing and 0.2ms ultra-low latency, the low profile Keychron Optical switches are crafted for typists or gamers who want to type at lightning speed with a 70 million lifespan much greater than industry standards.
*Low profile Keychron Optical switch keyboard is not compatible with any conventional mx style mechanical switch.
ALTERNATIVE KEYCAPS
We've spent over a year developing and implementing a MX-styled stem on both the low profile switches for the K3 as well as stabilizers on the big keys like the space bar, left Shift, backspace and Enter key.
It will improve reliability, deliver better typing experiences, and may potentially pave the way for other keycap manufacturers to launch alternative keycaps.
18 TYPES OF RGB
Comes with various RGB backlight settings, you can adjust the keyboard brightness to sync with your mood. Various backlight patterns are also available on the K3 White Backlight version.
