This month, I’ve been testing an extremely heavy keyboard while benchmarking various graphics cards and performing a bit of overclocking. Thankfully, nothing caught fire! When I first learned about Keychron's concrete keeb, specifically the K2 HE Concrete Edition, I was both intrigued and confused.

The marketing copy is certainly bold, claiming: "Each keystroke carries industrial rhythm, preserving the's concrete's solid core while elevating the experience with marble-like smoothness and auditory-visual harmony." With a description like that, I knew I had to try it for myself.

A Heavyweight Testing Experience

After requesting a review sample, I quickly realized just how heavy this device is. At 1.74 kg, the weight was quite a burden when I had to carry it home in my backpack after a long train ride and a walk from the station.

Despite the heft, I don't think this is a mere marketing gimmick. While you wouldn't want a concrete gaming mouse, extra weight in a keyboard can actually be a massive advantage. The K2 HE Concrete Edition feels incredibly well-built, with a perfectly formed outer shell and no visible moulding marks.

The build quality extends to the OSA double-shot keycaps, which feel rounded, crisp, and satisfyingly heavy. Connectivity is also seamless thanks to side-mounted switches that support:

  • USB Type-C
  • Bluetooth
  • 2.4 GHz wireless

The Performance of Keychron's Concrete Keeb

The keyboard stays anchored to my desk even during intense FPS sessions. While it doesn't sound drastically different from a standard keyboard, the stability and switch feel are remarkable. The included Gateron Double-Rail magnetic switches offer impressive technical specs:

  • Pre-lubed for maximum smoothness
  • 0.2–3.8 mm actuation range
  • 40 g starting force
  • Support for dynamic rapid trigger, last key priority, and adjustable actuation points

The resistance is perfect, providing a delicious weight that improves typing accuracy while remaining ultra-quick for gaming.

The Aesthetic Drawback

There is one issue preventing this from being my permanent daily driver, and it might sound silly: I really don't like the colour. Concrete isn't always the most aesthetically pleasing material, and even though Keychron matched the PBT keycaps to the frame, the resulting shade of grey just doesn't suit my setup.

My current rig is all black and red, making the Keychron's concrete keeb look out of place. Additionally, the RGB lighting is quite tame compared to my other peripherals.

Final Verdict

Even with the aesthetic mismatch, the quality is undeniable. At a $200 price tag, it is much more affordable than many high-end gaming keyboards that can cost significantly more. If you can get past the grey tone, the K2 HE Concrete Edition is an excellent choice for anyone who appreciates heavy-duty, premium hardware.
