Wireless and Wired
An excellent solution for multitasking. You can connect the K4 Pro with up to 3 devices wirelessly via its stable Broadcom Bluetooth 5.1 for seamless multitasking across your laptop, phone, and tablet. Switch among them swiftly, and it’s fully compatible with both Mac and Windows.
A reliable USB Type-C wired connection is also available when you need it.
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.
The Barebone version (without switch and keycap) is also available at your choice.
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.
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.
OSA Profile Double-shot PBT Keycaps
To further fine-tune your typing experience, the K4 Pro comes with our unique OSA profile (OEM profile with spherical-angle) and double-shot PBT keycaps that aim to provide a more comfortable fingertip feel with excellent oil resistance for long-term use on the timeless tenkeyless layout.
South-facing RGB Lights
The south-facing RGB is designed to better illuminate the keyboard backlight from the typist’s angle. The south-facing RGB is also free from interference when the user installs Cherry-profile alternative keycaps on their keyboard.
Comes with more than 22 types of RGB backlight settings (as well as a static white backlight option), and 14 types of backlight settings on the White Backlight version. You can further fine-tune the RGB hue, saturation, brightness, effect speed with ease.
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.

Customer Reviews
Really nice keyboard! Feels really good
Will you be surprised to find out the store "Keychron Germany" is located in China, ergo, subject to the Chinese New Year, both as customer support and logistics? I was. The fact affects the sipment cost too.
Making the long story short - Keychron K4 Pro is a decent product with negligible peculiarities.
It was delivered well packed.
It is solid, as "heavy". It is pleasant to type on with the switches of your liking. I personally changed the Keychron K Pro Red to silent ones for office use. It is VERY CUSTOMIZABLE. You may add button functions - I missed, so I added "Menu"="right mouse click". You may rearrange both button keycaps and functions. I changed the top-right 6 buttons to Ins, Del, Home, End, PgUp, PgDn which is much more natural order not only for me, but for the UseVIA.app team too.
It is high, which makes it hard to use for many of the present-day office workers. My good old arms support helps me handle this.
It is well made and well performing. But you have to spend some time and efforts to go through the not perfect Chinese service and user documentation:
- how many times in the recent decade have you come to a tracking URL missing the tracking code in it? AliExpress does it. Temu does it. I hope Keychron Germany can do it too.
- how many times have users struggled for the past 3 (three) years with the missing information in the Keychron user guides, regarding the Bluetooth pairing of multiple devices? The lack of any description or illustrations of the White Backlight version in the user guide is a minor detail.
There are only three additional keycaps coming with the keyboard. While the Keycap Puller is easy to use, the Switch Puller requires strong fingers and in most of the cases I preferred to use a generic one, instead of the metal spring one provided with the keyboard.
Be ready to pay close attention to:
- the positions of the BT/Off/Cable and Win/Android/Mac/ios switches
- handling the VIA online app https://usevia.app/ - it is quite easy to mess up. Two key points are A.) the different layers and B.) the instant change of button function. I incidentally changed the function of the Fn button, which limited severely the functionality of the keyboard - incl. no chance to reset it. It took me some time to figure out what had happened.
Nevertheless, it is a great basic keyboard even for most demanding users.
For additional ergonomics there are other Keychron models.

All I hoped it would be and then some!
