Back at CES 2026, we got a brief look at Keychron's resin and concrete K2 HE Special Edition wireless TMR keyboards, but the company has officially launched both the Concrete Edition and Resin Edition K2 HE keyboards, with both keyboards launching via Keychron's direct-to-consumer online store for $199.99. Both keyboards are based on the K2 HE, which has been one of Keychron's more popular models since it launched, and there isn't much by way of technical improvements over the original K2 HE aside from the design update. The resin edition features a smoky translucent case with an almost marbled aesthetic that shifts in the light, while the concrete edition has a simpler brutalist design, with color-matched keycaps and a solid gray aesthetic.

Both the K2 HE Concrete and Resin Editions are based on the same MCU, TMR sensor, and switch architectures as the original K2 HE, meaning they use the same Gateron Double-Rail Magnetic Nebula switches as the original—with 4 mm total travel and enabling all the typical analog features and online customization via Keychron Launcher—and feature the same 1 kHz polling rate and wireless connectivity via Bluetooth 5.3 and 2.4 GHz. It also goes without saying that both keyboards have the same 75% layout as the previous K2 HE keyboards. The material changes have also resulted in different dimensions. The K2 HE Resin Edition measures 321.13 × 131.3 mm, with a 27.06 mm listed front height and 4° typing angle, while the Concrete Edition comes in at 322.13 × 132.13 mm with a 27.39 mm front height and 4° typing angle. Both also use an aluminium switch plate and have a tray-mount design.
