This article covers エンドゲームギア(Endgame Gear) ゲーミングマウス XM2 8K v2 (エックスエムツー ハチケー ブイツー) 有線 8.

Overview

The Endgame Gear XM2 8K v2 is a wired gaming mouse specifically designed for claw grip users. Weighing just 52.5g, it achieves an ultra-light construction without compromising durability. The standout feature is its 8000Hz polling rate, enabled by the Nuvoton M483 MCU, which dramatically reduces input lag compared to standard 1000Hz mice. At its core sits a custom-tuned PAW3950 optical sensor, capable of up to 30,000 CPI with 0.1mm lift-off distance adjustment. The Kailh GX mechanical switches (SPDT) deliver an average response time of 70 microseconds, ensuring crisp and reliable click detection. The symmetrical shape with raised back and side indentations provides a secure grip for claw-style aiming.

Connectivity & Compatibility

The XM2 8K v2 uses a wired USB-A connection with a 1.8m flexible paracord cable. It is plug-and-play compatible with Windows, macOS, and Linux systems without requiring driver installation. However, to access full CPI and LOD customization, the Endgame Gear configuration software must be installed. To achieve the full 8000Hz polling rate, the host system should have a capable USB controller and sufficient CPU resources. Older PCs or laptops with limited USB bandwidth may not sustain 8000Hz consistently, resulting in automatic fallback to lower polling rates. The mouse works with all standard USB ports (USB 2.0 and above).

Product Info

The XM2 8K v2 was released in 2025 as an update to the original XM2 8K, refining the shape and sensor tuning. It is positioned as a high-end competitive gaming mouse, competing with the likes of Razer Viper Mini Signature Edition and Finalmouse Starlight-12. Its combination of sub-55g weight and 8000Hz polling gives it a unique edge in the ultra-light segment. The retail price is approximately ¥13,600 ( Japan). The package includes the mouse, a fixed paracord cable, two sets of PTFE mouse feet (small & large), and a quick-start guide. Warranty is typically one year from the manufacturer.

Best Use Cases

This mouse is ideal for competitive FPS players who use a claw grip and demand minimal latency. Games like Valorant, Counter-Strike 2, Overwatch 2, and Apex Legends benefit directly from the 8000Hz polling and precise sensor. Players who frequently perform flick shots, tracking, and rapid tapping will appreciate the low weight and responsive switches. It also suits enthusiasts who enjoy fine-tuning their gear. The adjustable CPI (200–30,000) and LOD (0.1mm steps) allow for personalized setups. The included spare skate set adds customization flexibility. For casual gaming or productivity tasks, the extreme specs may be unnecessary, and a more affordable 60–80g mouse could suffice.
