This article covers IROK MG75PRO 81キー 有線磁気スイッチ メカニカルキーボード ホール効果 8KHZ.

Overview

The IROK MG75PRO is a 75% layout (81-key) wired mechanical keyboard that leverages Hall-effect magnetic switches for ultra-low latency and adjustable actuation. Its CNC-machined aluminum alloy chassis provides rigidity and a premium feel, while the gasket mount structure combined with multiple layers of sound-dampening materials (PO sandwich foam, EPDM bottom foam, etc.) delivers a refined typing experience with reduced resonance. What sets the MG75PRO apart is its 8,000 Hz polling rate and 256 kHz single-key scan rate, translating to a mere 0.125 ms input delay. This makes it an excellent choice for competitive gaming where every millisecond counts. All keys are hot-swappable for magnetic switches (no soldering required), and the keyboard supports a web-based driver for key mapping, RGB customization, and actuation point adjustment down to 0.005 mm.

Connectivity & Compatibility

The MG75PRO connects via a USB-C to USB-A cable (included) and is compatible with Windows, macOS, and Linux out of the box. No additional drivers are needed for basic typing, but advanced features like key remapping, RGB lighting control, and actuation point tuning require the web-based or HUB driver software. Keycaps are ABS with side-printed legends, and a set of PBT keycaps is also included. The keyboard uses proprietary magnetic switches; standard Cherry MX-style mechanical switches are not compatible. Hot-swap functionality is limited to compatible magnetic switches (IROK brand or equivalent).

Product Info

The IROK MG75PRO launched in 2025 and sits in the mid-to-high tier of the gaming keyboard market. It offers flagship-level features such as 8KHz polling and a CNC aluminum frame at a price point under ¥20,000, delivering strong value. The warranty is typically one year (check local terms). The package includes the keyboard, USB-C cable, keycap puller, switch puller, spare PBT keycaps, and a manual.

Best Use Cases

Competitive FPS Gamers: The 8KHz polling and 0.005 mm actuation adjustment give a tangible edge in reaction-time-critical titles like Valorant, Apex Legends, and CS2. Not ideal for users who require wireless connectivity. Customization Enthusiasts: The gasket mount and multi-layer dampening provide a solid foundation for tuning the feel and sound. Swapping magnetic switches is easy, but Cherry MX compatibility is absent. * Minimalist Desk Setup Fans: The compact 75% layout frees up mouse space, and the CNC aluminum build adds a premium aesthetic. Not recommended for heavy data entry users who rely on a numpad.

Things to Consider

The most important caveat is that the MG75PRO uses magnetic switches exclusively — standard mechanical switches are not supported. Replacement switch availability is still limited, mostly to IROK's own offerings. The keyboard is wired-only, so it won't suit a fully wireless desk. The included ABS keycaps may develop shine over time, but the bundled PBT set offers a more durable alternative. The web driver requires an internet connection for customization. ## FAQ
Q: Can I use this keyboard with a Mac? A: Yes, basic typing works on macOS via USB. Advanced customization (RGB, key mapping) requires the web driver, which works on Mac as well. Q: How long do the magnetic switches last? A: While IROK doesn't publish a specific rating, Hall-effect switches have no physical contacts, so they typically outlast traditional mechanical switches (50-100 million keystrokes). Plus, they are hot-swappable for easy replacement. Q: What PC specs are recommended for full 8KHz polling? A: To avoid USB controller bottlenecks, a modern mid-range or better CPU is recommended. Older or low-power systems may experience increased latency under 8KHz polling.
