This article covers エンドゲームギア(Endgame Gear) ゲーミングマウス XM2w 4K ダークフロスト EGG-XM2W-4K-DF.

Overview

The Endgame Gear XM2w 4K Dark Frost is the latest wireless flagship from the German esports-focused brand, building on the legacy of the acclaimed XM series. Designed specifically for claw and fingertip grips, its symmetrical shape features a distinctive reverse-tapered waist that locks the thumb and ring finger into place for exceptional control. The bundled 4K dongle supports polling rates up to 4000Hz out of the box, delivering wired-like responsiveness without the cable. At its core, the XM2w 4K employs the PixArt PAW3395 optical sensor, capable of 26,000 CPI, 650 IPS, and 50G acceleration. Combined with a lightweight build (approximately 60g) and low click latency, this mouse is engineered for competitive play where every millisecond counts.

Connectivity & Compatibility

Wireless connectivity is exclusively 2.4GHz via the included USB dongle — there is no Bluetooth or wired mode. The dongle uses a standard USB-A connector and is pre-paired with the mouse. Compatible with Windows 10/11, macOS, and Linux. Plug-and-play; no additional software is required for basic operation, though the Endgame Gear software suite allows for CPI adjustment, button remapping, and firmware updates. * The polling rate can be cycled between 4000Hz, 2000Hz, and 1000Hz by holding the mode button on the underside of the mouse.

Product Info

Released in late 2024, the XM2w 4K Dark Frost carries a retail price of approximately $100–$110 USD / ¥15,000–¥16,000 JPY, placing it in the upper-mid range of the wireless gaming mouse market. The package includes the mouse, the 4K dongle, a USB-C charging cable, grip tape, and a quick-start guide. Endgame Gear offers a 2-year warranty. In terms of market positioning, the XM2w 4K directly competes with the Razer Viper V2 Pro and Logitech G PRO X SUPERLIGHT 2, but differentiates itself through its claw-grip-optimized shape and the inclusion of a 4000Hz dongle at no extra cost. It is a purpose-built tool for competitive gamers who prioritize grip stability and low latency over RGB lighting or multi-device connectivity.

Best Use Cases

Competitive FPS players: The 4000Hz polling rate reduces input lag to sub-millisecond levels, which is especially beneficial in fast-paced shooters like Valorant, CS2, and Apex Legends. The claw-grip shape promotes consistent aim and quick flicks. Claw/fingertip grip users: If you naturally hold your mouse with your fingertips rather than palming it, the XM2w 4K's contoured sides will feel intuitive and secure. The lightweight design reduces fatigue during long gaming sessions. * Esports enthusiasts seeking a clean wireless setup: The included 4K dongle eliminates the need for a separate receiver purchase, and the lack of a cable keeps the desk clutter-free without sacrificing performance. However, palm-grip users or those with larger hands may find the XM2w 4K too small or restrictive. In such cases, consider the Endgame Gear OP1 series or a larger ambidextrous mouse like the Razer DeathAdder V3 Pro.

Things to Consider

The XM2w 4K is wireless-only — there is no wired mode for charging and playing simultaneously. While you can use the mouse while it charges via the USB-C cable, the cable itself is not designed for competitive use. Running at 4000Hz polling rate increases CPU overhead. On lower-end processors (e.g., Intel Core i3 or older Ryzen 3), this may cause slight frame-time spikes in CPU-bound games. If your system is older, consider dropping to 1000Hz or 2000Hz. The symmetrical design features side buttons only on the left side, making it a right-handed-only mouse. Left-handed users should look for an ambidextrous model with buttons on both sides. Battery life is rated at approximately 70 hours at 1000Hz; expect significantly less at 4000Hz. Full recharge via USB-C takes about 1–2 hours.
