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.

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. 

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.

Two level adjustable rubber feet makes the new K3 more comfortable to type on. 

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.

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.

We’ve overcome different technical challenges to redesign both the low profile Gateron Mechanical switch and low profile Keychron Optical switch in order to elevate the typing experience while enhancing its reliability on the ultra-slim keyboard.
