This article covers ENDGAME GEAR (エンドゲームギア) XM2 8K v2 ゲーミングマウス ホワイト.

Overview

The ENDGAME GEAR XM2 8K v2 is a wired gaming mouse built from the ground up for competitive FPS players. Its headline feature is the incredibly low 51.5g weight, combined with a PixArt PAW3950 optical sensor capable of 30,000 CPI and a true 8000Hz polling rate. This combination minimizes input lag to an absolute minimum, giving you every possible millisecond advantage in fast-paced shooters. Designed specifically for claw grip users with medium to large hands, the symmetrical shell features a wide rear and gently curved sides for a secure, locked-in feel. While it is a wired-only mouse, the included Flex Cord 6.0 cable is exceptionally soft and lightweight, making it feel nearly wireless when used with a mouse bungee.

Connectivity & Compatibility

Connection is via USB-A wired only. There is no wireless mode, so this mouse is not suitable for users who want a completely cable-free desk setup. Polling rate is adjustable via software: 8000Hz, 4000Hz, 2000Hz, or 1000Hz. Running at 8000Hz increases CPU overhead slightly, so a reasonably modern PC is recommended. Officially supports Windows 10 and 11. The configuration software does not run on macOS. Cable length is approximately 1.8m (6 feet).

Product Info

The XM2 8K v2 is a refined version of the original XM2 8K, released in 2025. It sits in the high-end competitive segment, priced around $90 USD / ¥13,000 JPY. The manufacturer offers a 2-year warranty. The package includes the mouse, two sets of replacement skates (standard and hybrid), and a manual. By omitting wireless hardware, ENDGAME GEAR has kept the weight ultra-low and the price competitive. Compared to similarly priced wireless mice, you trade the convenience of no cable for lower weight, no battery anxiety, and potentially lower latency.

Best Use Cases

Competitive FPS players (Valorant, CS2, Apex Legends): The 8000Hz polling and 51.5g weight provide a tangible advantage in flick shots and tracking. The claw-grip-optimized shape gives excellent control for players who prefer a more aggressive grip style. Gamers who prefer wired peripherals: If you dislike managing battery levels or worry about wireless interference, this mouse offers a hassle-free experience with near-zero cable drag thanks to the flexible cord. * Users with medium-to-large hands seeking an ultralight mouse: While many sub-60g mice exist, few are specifically shaped for claw grip at this weight point. Users with hands 18cm or larger will find the XM2 8K v2 particularly comfortable.
