This article covers ENDGAME GEAR (エンドゲームギア) XM2w 4k v2 ワイヤレスゲーミングマウス ホワイト フロスト.

Overview

The ENDGAME GEAR XM2w 4k v2 is a wireless gaming mouse built for competitive gamers who demand low latency and a claw-optimized shape. Weighing just 63g, the symmetrical shell accommodates medium-to-large hands while keeping the mouse light enough for fast, flicky movements. At its core is the PixArt PAW3950 optical sensor, supporting up to 30,000 CPI, 750 IPS, and 50G acceleration. The lift-off distance (LOD) can be finely adjusted from 0.7mm to 1.7mm. The true standout feature, however, is the native 4000Hz wireless polling rate, which can be downgraded to 2000Hz, 1000Hz, or 125Hz. Wired mode caps at 1000Hz but ensures near-zero interference. GX switches, individually sorted before assembly, provide a crisp tactile feel and are rated for 80 million clicks. The White Frost finish gives the mouse a clean, understated look that fits almost any desk setup.

Connectivity & Compatibility

The XM2w 4k v2 connects via 2.4GHz radio using the included USB dongle. Pairing is instant when the dongle is inserted into a PC. For wired use, a 1.8m (6 ft) USB Type-A to C Flex Cord 7.0 cable is included, which offers a drag-free experience thanks to its flexible paracord-like material. Compatibility spans Windows, macOS, and Linux. The mouse can be fully configured using ENDGAME GEAR’s official software, allowing adjustments to CPI steps, LOD, polling rate, and button remapping. No special drivers are required for basic operation—plug and play works on most systems.

Product Info

Released in late 2025, the XM2w 4k v2 is an iterative upgrade to the already well-regarded XM2w series. It sits squarely in the high-end wireless gaming mouse segment, competing with the Logitech G Pro X Superlight 2 and Razer Viper V3 Pro. Its main differentiator is the combination of 4000Hz wireless polling and a relatively lower price tag while maintaining top-tier sensor performance. The warranty period is typically 2 years (check official website for exact terms). The package includes the mouse, USB dongle, charging/data cable, and a quick-start guide. Additional grip tape and replacement mouse skates are sold separately.

Best Use Cases

  1. Claw-grip FPS players The XM2w 4k v2 is engineered for claw grip. The wide rear curves and indented sides offer excellent stability during rapid horizontal movements, making it ideal for games like Valorant and CS2. If your hand size is smaller or you strictly use palm grip, consider ergonomic alternatives. 2. Competitive gamers seeking minimum latency 4000Hz polling means inputs are sampled every 0.25ms. For players with high-refresh-rate monitors (240Hz+) and the ability to exploit this responsiveness, the difference in aim correction or reaction can be tangible. However, the benefit is marginal at 144Hz or below, so not everyone needs this feature. 3. Lightweight mouse enthusiasts 63g is undeniably light for a wireless mouse, and the balance is neutral. This makes flicks, 180-degree turns, and rapid lifts effortless. Users accustomed to heavier mice (80g+) may initially find it too light, but adaptation is usually quick. 4. Left-handed users needing an ambidextrous shape The symmetrical profile allows left-handed operation, though the side buttons are placed on the left side only. Left-handed users would need to remap or use the buttons with their right index finger, which is workable but not ideal for true ambidextrous use. True ambidextrous mice with buttons on both sides (like the Razer Viper V3 Pro) might be a better fit.
