This article covers エンドゲームギア(Endgame Gear) XM2 8K ゲーミングマウス 8000Hz ポーリングレート Kailh GX スイッチ PixArt PAW3395センサー 52g ホワイトフロスト.

Overview

Endgame Gear's XM2 8K is a wired competitive gaming mouse designed to push input latency to the absolute minimum. Its headline feature is an 8000Hz polling rate — eight times the standard 1000Hz — which translates to roughly 0.125ms of theoretical latency. Under the hood, the PixArt PAW3395 optical sensor delivers up to 26,000 CPI and 650 IPS tracking. The main clicks use Kailh GX switches, offering a crisp, tactile response with a rated lifespan far beyond typical Omron designs. The shell weighs just 52 grams, making it one of the lightest production mice on the market. The White Frost variant reviewed here features a translucent white coating that gives a clean, understated look.

Connectivity & Compatibility

The XM2 8K connects exclusively via a USB-C to USB-A cable — no wireless option. The included paracord-style cable is flexible and minimizes drag, even in fast-paced games. OS support is officially Windows 10 and later; the 8000Hz polling rate and customization software are Windows-only. The mouse works as a basic HID device on macOS and Linux, but you'll lose high-polling advantages. The bottom houses large PTFE feet, and a secondary set of smaller skates is included, letting you dial in the glide feel to your preference.

Product Info

Released in late 2024, the XM2 8K sits at the high end of the wired gaming mouse market. MSRP is $99.99 on the official Endgame Gear store, and it's widely available on Japan for around ¥9,980. The package includes the mouse, a 1.8m USB-C cable, a spare skate set, and a manual. The warranty is two years from purchase. Endgame Gear is a German brand known for close collaboration with esports professionals, and their products are sold primarily through their own web shop and select retailers.

Best Use Cases

Competitive FPS players: The 8000Hz polling and 52g weight make the XM2 8K a top choice for Valorant, CS2, and Apex Legends. The low-latency input gives a tangible sense of responsiveness, especially on high-refresh monitors. Not ideal for those who prefer heavier mice or wireless convenience. Lightweight mouse newcomers: If you've never used a sub-60g mouse, the XM2 8K is a great entry point. Its rigid shell and decent side grips inspire confidence, and the cable is light enough that you won't immediately miss wireless. Do note that 8000Hz can increase CPU overhead; older systems might see stuttering in CPU-bound titles. Tinkerers and enthusiasts: The swappable skate system and on-board memory for DPI/polling profiles make this mouse highly customizable. The software is lean, doesn't run in the background, and lets you save settings directly to the mouse. For players who want to fine-tune every aspect of their aim, the XM2 8K delivers.
