Overview

  • 2.4 GHz & Bluetooth Connection
    Experience peak gaming performance on the fly with the K4 HE’s 2.4 GHz wireless connection boasting a rapid 1000 Hz polling rate. For seamless multitasking across your computer, phone, and tablet, you can effortlessly connect the K4 HE via Bluetooth 5.2 to three devices.
  • Gateron Double-Rail Magnetic Switches
    Keychron K4 HE comes with pre-lubed Gateron double-rail magnetic switches for an ultra-stable and ultra-responsive typing experience with an industry-leading, lightning-fast response time, and precise control over the way your keyboard feels and responds. Jump into action with unmatched smoothness and stability.
  • Last Keystroke Prioritization (LKP) & Snap Click
    LKP allows seamless directional changes by prioritizing the last key pressed, ensuring smoother gameplay in titles like Valorant. With Snap Click, deeper keypresses take precedence when two keys are hit at once, automatically resetting shallower presses.
  • Dynamic Rapid Trigger
    Activate or deactivate keys based on how far they travel, not predefined points. This means immediate key reactions—press to activate, release to reset—allowing for faster, more precise keystrokes. In rapid gameplay, this translates to executing complex actions in real-time without delay, giving you a serious advantage during fast-paced sequences.
  • Program with QMK & Launcher.
    The open-source QMK firmware means endless possibilities for key remapping, macros, shortcuts, and more. With the Keychron Launcher web app, you can effortlessly remap keys, adjust actuation points, set the magnetic switches, and create personalized macro commands, shortcuts, and key combinations for each key.

Amazing keyboard - I’m used to lightweight and bigger wireless keyboards (specifically the Logitech G613). This one, however, has changed my perspective. It’s the total opposite to me. It’s very heavy and smaller. The keys though, are amazing. It’s been amazing to game on. I use this for work and for gaming and nothing about it gets tiring. It’s a change for me but I feel most people don’t hastily choose a different keyboard and give it a bad review. I’ve been using this for over a year and wouldn’t choose another, right now. I use it simultaneously with my PC and MacBook. It’s truly amazing. I’ve recommended it to multiple of my coworkers and friends.

Best Keyboard I've Owned - For context, I went from an Logitech G915, and I hated the cheap feeling keys and presses. Then I went to a cheap Chinese mechanical keyboard by Huion, which felt worlds better at the fraction of the cost, but it had freezing issues. Now I'm on this keyboard, still going strong after nearly a year. To be clear, the keys feels great, but I do wish they felt a bit smoother or softer at the price? and perhaps I'd not choose this key layout again as I find myself hitting Numpad 0 instead of right arrow more often than I'd like. But would I recommend? 100% if you find it on sale. I'm unfortunately not someone whos tried a bunch of the newest enthusiast mechanical keyboards, so I can't say whether its THE best at this price. But the software and hardware is dang good and its frame is metal, not some cheap plastic.

End-game Keyboard - I am extremely picky with keyboards and tend to return the majority of them. This one I knew I’d keep in just a few seconds of using it. The keyboard feels premium, but without being too heavy. The switches sound nice and are not too loud or quiet. The keyboard is responsive and looks very clean in person. Literally zero complaints. Well, maybe a critique is it gets rather dusty. I also recommend the compatible Keychron wrist wrest (purchased separately)!
