WIRED Review: Keychron K2 HE Concrete Edition Offers Solid Typing Amidst Novelty
A recent assessment by WIRED highlights the durability and acoustic properties of the K2 HE, while noting interoperability issues and maintenance challenges associated with the unsealed material.
WIRED has published a review of the Keychron K2 HE Concrete Edition, a mechanical keyboard distinguished by a case constructed from raw, unsealed concrete with embedded metal posts. The publication describes the device as a "conversation piece" that delivers a solid typing experience and a deep, resonant sound profile, contrasting it with the company’s previous all-ceramic model which was criticised for lacking refinement. The review notes that while the concrete construction provides significant durability and a unique aesthetic, the material is prone to staining and smudging, requiring users to accept a developing patina.
The keyboard utilises standard Hall Effect (HE) switches rather than the Tunneling Magnetoresistance (TMR) switches found in Keychron’s earlier ceramic iteration. These switches operate at a 1,000 Hz polling rate and offer software-level customisation through the Keychron Launcher app, including adjustable actuation distance, Rapid Trigger, and "Snap Tap" functionality. The latter, which prioritises the most recently pressed opposing key to aid in counter-strafing, is noted as being banned in some competitive gaming matches due to its advantage in movement mechanics.
Acoustically, the concrete case contributes to a pleasantly rounded, deep tone that differs from typical mechanical keyboards. The reviewer observed that the porous nature of the material absorbs harsher sensations at the bottom of the keypress, creating a slight softness without feeling mushy. Stabilizers are PCB-mounted and factory-lubricated, providing smooth and consistent performance, although the review highlighted excessive lubricant clumps on the outside housings as a minor manufacturing oversight.
A significant drawback identified in the assessment is the lack of interoperability within the current market. Keychron’s HE switches utilise a proprietary design that is incompatible with other brands, such as Wooting, which employ a more common HE standard. This fragmentation is described as a frustration for enthusiasts accustomed to the customisability of traditional MX-style mechanical keyboards, where aftermarket components are widely interchangeable.
Despite the novelty of the material, the review concludes that the K2 HE is a genuinely well-made device that justifies its existence through performance. It is noted as the first widely available concrete keyboard with rapid shipping, distinguishing it from previous DIY or limited-run options. The device is described as heavy and difficult to break, appealing to users who prioritise durability and a distinct industrial aesthetic over portability or conventional electronics design.
