This article covers エンドゲームギア(Endgame Gear) OP1 8K v2 有線 ゲーミングマウス 8000Hz ポーリング Kailh GXスイッチ ホワイト EGG-OP1-8K-V2-WHT.
Overview
The Endgame Gear OP1 8K v2 is a wired gaming mouse built for competitive play. Its standout feature is the 8000Hz polling rate, powered by a Nuvoton M483 MCU, which minimizes input lag to an extreme degree. It also uses a custom PixArt PAW3950 optical sensor, offering fine-grained CPI and lift-off distance adjustments. This mouse features Kailh GX mechanical switches co-developed with Endgame Gear, allowing users to switch between 'GX Speed Mode' for faster response and 'GX Safe Mode' to prevent chattering. The click latency is rated at an average of 70 microseconds, with Speed Mode reducing it by about 1.4 milliseconds. The shell is designed for claw grip, with flat sides and extended main buttons for better control.
Connectivity & Compatibility
The OP1 8K v2 connects via a flexible paracord cable (Flex Cord 5.0) and is compatible with Windows 10/11. The dedicated software lets you adjust CPI, polling rate, button assignments, and LOD. Polling rate can be cycled through 8000Hz, 4000Hz, 2000Hz, and 1000Hz by holding the button on the bottom of the mouse.
Product Info
Released in late 2025, the OP1 8K v2 retails for around ¥13,600. The package includes the mouse and a set of larger replacement skates. This is a high-end wired mouse for competitive gamers, packing features like 8000Hz polling, a custom sensor, and hot-swappable switches.
Best Use Cases
Competitive FPS players: The 8000Hz polling and ultra-low click latency provide a tangible advantage in fast-paced shooters like Valorant, CS2, and Apex Legends. Note that 8000Hz can be CPU-intensive, so a high-end processor is recommended. Claw grip enthusiasts: The flat sides and compact shape are ideal for claw grip users. The design accommodates a wide range of hand sizes comfortably. * Customization fans: The hot-swappable switch sockets let you easily change switches without soldering, allowing you to tailor the click feel to your preference.
Things to Consider
This is a wired-only mouse, so it won't suit those who prefer wireless freedom. To fully benefit from 8000Hz polling, you need a compatible game and a capable CPU; on lower-end systems, the advantage may be negligible. While the cable is flexible, some users may still find a wire inconvenient and should consider wireless alternatives.
