This article covers 【国内正規品】Keychron K2 HE ラピッドトリガー ワイヤレス カスタムキーボード.

Overview

The Keychron K2 HE is a 75% wireless mechanical keyboard that merges traditional keyboard craftsmanship with Hall Effect magnetic switch technology. It features Gateron double-rail magnetic switches with 0.1mm actuation point adjustment and rapid trigger support, making it a strong contender for competitive gaming. The aluminum frame is paired with natural rosewood side panels, available in light or dark wood finishes depending on the color variant.

Connectivity & Compatibility

The K2 HE supports three connection modes: 2.4GHz wireless (with included dongle), Bluetooth 5.2, and USB-C wired. All modes offer 1000Hz polling rate for low-latency performance. It is compatible with Windows, macOS, and Linux, and can be customized via the Keychron Launcher web tool for key remapping, macros, and actuation point adjustments without installing software.

Product Info

Released in 2025, the K2 HE sits in Keychron's mid-to-high-end custom keyboard lineup. Priced at approximately ¥27,940 on Japan, it includes a Type-A to Type-C cable, keycap puller, switch puller, and hex wrench. The double-shot PBT keycaps ensure long-lasting legends, and the hot-swap socket supports only Gateron double-rail magnetic switches.

Best Use Cases

Competitive gamers: The rapid trigger and 0.1mm actuation adjustment provide an edge in FPS and fighting games. However, users accustomed to optical or capacitive switches should note the magnetic switch feel. Custom keyboard enthusiasts: Hot-swap capability and QMK/VIA-compatible firmware allow deep customization. The 75% layout retains function keys while saving desk space. * Multi-device users: Seamless switching between up to three devices via 2.4GHz, Bluetooth, and USB-C makes it ideal for desktop, laptop, and tablet setups. ## Alternatives
Direct competitors include the Razer Huntsman V3 Pro (optical switches) and Wooting 60HE+ (magnetic switches). The Keychron K2 HE differentiates with its 75% layout, natural wood side panels, and QMK/VIA customization. However, it occupies slightly more desk space than 60% models like the Wooting.
