Upgraded Typing Experience

The K4 Pro has been re-engineered and redesigned from the inside out to upgrade the typing experience. The added sound-absorbing foam, a thick silicone dampening bottom pad, and steel plate provide responsive feedback and a peaceful typing sound, while added weight will enhance the stability.

Suitable For All Devices

Offers a Mac layout while still being compatible with Windows, the K4 Pro is one of the few on the market that has the same multimedia and function key functions as Apple keyboards for Mac users, but with more tactile feedback.

You can even configure different keymaps for both Mac and Windows devices. While VIA software is compatible with macOS, Windows, and Linux. Includes keycaps for both macOS and Windows (3 keycaps for each) to allow you to switch between operating systems with ease.

Hot-Swappable

Every detail matters, so we make the K4 Pro hot-swappable for your personalized typing experience. The hot-swappable sockets are mounted on the PCB, so you can hot-swap every switch on the K4 Pro with almost all of the 3pin and 5pin MX style mechanical switches on the market (including Cherry, Gateron, Kailh, Panda, etc.) without soldering. You can customize your own typing experience in seconds.

Keychron K4 Pro ISO PCB Screw-in stabilizers

Screw-In PCB Stabilizers

Even small part matters for your fingertip feel. We’ve integrated the PCB-mounted screw-in stabilizers for a smoother typing experience with less wobbliness on the big keys such as space bar, shift, enter, and backspace. The Keychron K4 Pro also supports third-party screw-in PCB stabilizers.

OSA Profile ABS Backlight Shine-Through Keycaps

To further leverage your typing experience, the K4 Pro ISO version comes with our unique OSA profile (OEM profile with spherical angle) and ABS keycaps that aim to provide a more comfortable fingertip feel and a fantastic backlight shine-through effect.

Pre-lubed Keychron K Pro Switch

By optimizing the switch mold, the K Pro switch wobbles less than a standard mechanical switch and feels smoother on each hit. Plus, the factory pre-lubed process on all the K Pro switches (exclude the clicky ones), no doubt this will ensure the best smoothness at your fingertips when typing.

Keychron K Pro mechanical switch features

Ergonomic Support

Three levels of adjustable typing angle (3º, 7º & 10º) and curved OSA-profile keycaps are all working together to provide long-lasting ergonomic support for your wrist.
