This article covers エンドゲームギア(Endgame Gear) OP1w 4K ワイヤレスゲーミングマウス 4000Hz ポーリングレート Kailh GXスイッチ PixArt PAW3395 センサー ダークフロスト EGG-OP1W4K-DF.

Overview

The Endgame Gear OP1w 4K is a wireless gaming mouse engineered for ultra-low latency. It supports a polling rate of up to 4000Hz thanks to the included dedicated USB dongle, delivering noticeably smoother cursor movement compared to standard 1000Hz mice. The PixArt PAW3395 sensor provides tracking up to 26,000 CPI, 650 IPS, and 50G acceleration, making it a strong choice for competitive play. Main buttons feature Kailh GX switches with a unique SPDT design that offers both a low-latency “Speed Mode” and a safer “Standard Mode.” The mouse also uses a dry-grip coating to maintain control even during intense, sweaty sessions.

Connectivity & Compatibility

The OP1w 4K connects wirelessly via 2.4GHz using the bundled 4K dongle, or wired via USB-C. The wireless dongle includes a built-in extension adapter to keep it close to the mouse for optimal signal. If the battery runs low, the included paracord cable (Flex Cord 4.0) lets you continue using it as a wired mouse without interruption. Compatibility is primarily with Windows PCs; basic functionality works on macOS and Linux, but configuration software is Windows-only. Endgame Gear recommends keeping the mouse within 20cm of the dongle for the best wireless performance.

Product Info

The Endgame Gear OP1w 4K is a high-end wireless gaming mouse aimed at competitive players and esports enthusiasts. It launched in late 2024 with a retail price of approximately ¥10,880 (tax included), offering strong value for its feature set. The Dark Frost variant features a translucent shell that shows the internal PCB, giving it a distinctive look. Accessories include the 4K dongle, paracord USB-C cable, a set of large replacement skatez, and a screwdriver for swapping the main switches. Warranty details should be confirmed with the manufacturer.

Best Use Cases

Ideal for FPS and battle royale players who need every millisecond advantage. The 4000Hz polling rate and Kailh GX switches minimize click-to-actuation delay, giving you a direct edge in fast-paced encounters. Suited for claw-grip users and those with small to medium hands. Compared to the XM series, the OP1w 4K is shorter and narrower, allowing a more relaxed or precise grip. * A great choice for gamers who want wired-like responsiveness without the cord. The 30-hour battery life at 4000Hz is practical for daily use, and the option to switch to wired mode during charging means you never have to stop playing.
