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. 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. *Hot-swappable feature is available for low profile Keychron Optical switch version only.
