This article covers エンドゲームギア(Endgame Gear) ゲーミングマウス XM2 8K V2 有線 8.

Overview

The Endgame Gear XM2 8K V2 is a wired gaming mouse built with one clear mission: deliver the lowest possible input latency for competitive esports. Weighing just 51.5 grams, it achieves an almost absurd level of lightness while supporting a blistering 8000Hz polling rate — eight times the standard 1000Hz found on most gaming mice. At its core sits a custom-tuned PixArt PAW3950 optical sensor, capable of up to 30,000 CPI with 0.1mm adjustable lift-off distance. The main clicks use Kailh GX mechanical switches co-developed with Endgame Gear, rated for an average response time of just 70 microseconds. This is a mouse that leaves no room for excuses.

Connectivity & Compatibility

The XM2 8K V2 connects exclusively via USB, using a flexible 1.8-meter paracord cable that minimizes drag during fast flicks. It works natively on Windows 10 and 11, where the full 8000Hz polling rate and configuration software are available. macOS users can use it as a basic pointing device, but advanced features require Windows. Two sets of mouse feet are included in the box: standard small skates and larger coverage skates, letting you fine-tune glide feel depending on your mousepad surface.

Product Info

Released as a refined version of the XM2 8K in 2025, this V2 iteration sits firmly in the high-end tier of wired gaming mice. Its entire design philosophy revolves around weight reduction and latency minimization — areas where wireless mice still can't fully compete due to battery and radio overhead. The mouse carries a 2-year manufacturer warranty. In the box you'll find the mouse, an extra set of large mouse skates, and a quick-start guide.

Best Use Cases

First and foremost, this mouse is for competitive FPS players — think Valorant, CS2, or Apex Legends at a high level. The 8000Hz polling rate only makes sense when paired with a 240Hz or faster monitor; otherwise, the benefit is largely wasted. Second, it's ideal for users who prioritize ultra-lightweight hardware. At 51.5g, the XM2 8K V2 is significantly lighter than almost any wireless alternative, reducing wrist fatigue during long sessions. Finally, claw-grip users will find the shape particularly accommodating. The raised rear hump and pronounced side grooves provide a secure, locked-in feel that suits aggressive fingertip-and-claw hybrids.
