This article covers エンドゲームギア(Endgame Gear) ゲーミングマウス XM2w 4K ホワイト ワイヤレス EGG-XM2W-4K-WHT.

Overview

The Endgame Gear XM2w 4K (model EGG-XM2W-4K-WHT) is the latest wireless iteration of the acclaimed XM series, designed specifically for claw and fingertip grip users. This white variant ships with a dedicated 4000Hz polling rate USB-C dongle right in the box. It features a symmetrical shape with a pronounced rear hump and concave side contours that lock the thumb and ring finger into place. The result is a remarkably stable grip that minimizes micro-adjustments during intense aiming, making it a strong contender in the competitive wireless mouse space.

Connectivity & Compatibility

The XM2w 4K connects via 2.4GHz wireless using the included USB-C dongle. The dongle supports up to 4000Hz polling, adjustable down to 2000Hz or 1000Hz by holding the mode button on the mouse underside. Wired operation is also supported via the USB-C to USB-A cable, allowing simultaneous charging and use. The interface is USB-C on the mouse side and USB-A on the PC side.

Product Info

Released in late 2024, the XM2w 4K sits in the mid-to-high tier of the gaming mouse market. Despite including a 4000Hz dongle as standard, its street price remains competitive at around ¥11,900 in Japan. The package includes the mouse, 4K dongle, USB-C to USB-A cable, replacement glide feet, and manual. Warranty details are available on the manufacturer's official website.

Best Use Cases

First and foremost, this mouse is built for FPS players who use a claw or fingertip grip. The concave sides and generous rear shape provide exceptional stability during rapid flicks and tracking, reducing the need for conscious grip correction. Second, it's ideal for gamers who demand the lowest possible wireless latency. The 4000Hz polling rate delivers visibly smoother cursor movement compared to standard 1000Hz mice, especially when paired with a high-refresh-rate monitor. However, users with large hands or those who prefer a palm grip may find the XM2w 4K too small. In that case, consider the Endgame Gear OP1 series or larger ergonomic alternatives from other brands.

Things to Consider

Being a symmetrical design, it may feel unfamiliar to users accustomed to right-handed ergonomic mice. Battery life also decreases noticeably at 4000Hz compared to 1000Hz, so daily charging may be necessary for heavy users. Wireless connectivity is limited to 2.4GHz only — there is no Bluetooth support, which could be a drawback for users who switch between multiple devices. Direct competitors include the Razer DeathAdder V3 Pro and Logitech G PRO X SUPERLIGHT 2, both also offering 4KHz polling. The XM2w 4K differentiates itself through its claw-grip-optimized shape, making fit the single most important factor in your decision.
