This article covers 【国内正規品】Keychron K2 Pro ワイヤレス・カスタムメカニカルキーボード.

Overview

The Keychron K2 Pro is a wireless mechanical keyboard that packs a 75% layout, hot-swappable switch sockets, and deep firmware programmability via QMK/VIA into a compact chassis. Distributed in Japan by Copeck, this board runs on Bluetooth 5.1 for multi-device pairing and includes a USB-C port for low-latency wired use. It ships with factory-lubricated Keychron K Pro switches (blue tactile in this variant) and double-shot PBT keycaps in an OSA profile, giving a premium typing feel straight out of the box. The K2 Pro is clearly aimed at users who want customization without compromises — whether you are a programmer, writer, or multi-OS worker.

Connectivity & Compatibility

The keyboard uses a Broadcom Bluetooth 5.1 chipset that remembers up to three devices, allowing seamless switching between a MacBook, a Windows PC, and a tablet with a single press. On the wired side, the USB-C connection delivers a stable, low-latency link suitable for gaming or high-security environments. The board ships with both Mac and Windows keycap sets and a physical OS-switch slider, so you can flip between layouts instantly. Linux users can also remap everything using the open-source VIA software. It complies with Japan's radio law (Technical Conformity).

Product Info

Priced around the ¥15,950 range on , the K2 Pro occupies a mid-to-upper tier in the mechanical keyboard market. Its main differentiator in this bracket is the combination of wireless connectivity and QMK/VIA customization — a rarity at this price point. The package includes a USB-C cable, keycap and switch pullers, and two full sets of keycaps (Mac and Windows). Warranty is handled by the authorized Japanese distributor for one year. The K2 Pro can also be purchased directly from the Keychron website and select electronics retailers.

Best Use Cases

Multi-device professionals: If you juggle a Mac at work, a Windows desktop at home, and an iPad on the go, the K2 Pro's Bluetooth 5.1 tri-pairing and instant OS switch will save you the hassle of swapping keyboards. Not ideal for those who only use one device — you could get a cheaper wired board. Customization enthusiasts: Hot-swappable sockets let you try any MX-style switch without soldering, while QMK/VIA opens endless key-mapping possibilities. Perfect for those who like to tweak their typing feel or create productivity macros. If you never plan to change switches, a simpler keyboard might be sufficient. * Typing-quality seekers: The combination of PBT keycaps, factory-lubed stabilizers (screw-in), and the distinctive OSA profile delivers a smooth, stable typing experience for long sessions. Blue-switch users should note that the tactile model is not pre-lubed, but the switches are still smoother than most stock offerings. Gamers who prioritize polling rate over feel might prefer a dedicated gaming board with 1000Hz wireless.
