This article covers エンドゲームギア(Endgame Gear) XM1r ゲーミングマウス PAW3370センサー 50~19.

Overview

The Endgame Gear XM1r is a wired gaming mouse from the German peripheral brand, built around the PixArt PAW3370 optical sensor. It supports up to 19,000 CPI and a 1,000 Hz polling rate, while the symmetrical shell weighs only about 70 grams — a clear nod to competitive gamers who prioritize swift, fatigue-free aiming. Main buttons use Kailh GM 8.0 switches rated for 80 million clicks, delivering a crisp and responsive feel that suits rapid tapping in fast-paced shooters. The paracord-style cable is flexible and lightweight, reducing drag during intense sessions even without a mouse bungee. The XM1r has earned a strong reputation among FPS and tactical shooter players who value low weight and reliable tracking.

Connectivity & Compatibility

The XM1r connects via a wired USB 2.0 (Type-A) interface; there is no wireless option. It works plug-and-play on Windows 10 and later, macOS, and Linux without additional drivers. For advanced customization — CPI steps, lift-off distance, and button remapping — Endgame Gear provides a dedicated software utility (English UI only). The cable is approximately 2 meters long, offering enough reach for both desktop and laptop setups. Large PTFE feet come pre-installed on the bottom, providing smooth gliding on cloth mouse pads. The mouse is compatible with any standard USB-A port, so no adapter or hub is required.

Product Info

Released in 2021, the XM1r remains widely available through Endgame Gear's official store and major retailers like . Its street price hovers around ¥5,000, placing it in the mid-range segment for wired gaming mice. The manufacturer offers a standard 2-year warranty. The package includes only the mouse itself; replacement feet and additional grip tape are sold separately. Market positioning: an entry-to-mid-tier wired gaming mouse that balances lightweight design with flagship-grade sensor performance. By omitting wireless circuitry and RGB lighting, Endgame Gear keeps the cost low while delivering the core features that matter most to competitive players.

Best Use Cases

Competitive FPS players: The combination of a 70g body and the PAW3370 sensor enables precise micro-adjustments and quick target acquisition. Titles like Valorant, CS:GO, and Apex Legends benefit directly from the low weight and high tracking accuracy. However, users accustomed to heavier mice (90g+) may find the XM1r too light initially. Users who prefer symmetrical shapes: Unlike ergonomic right-handed designs, the symmetrical shell offers more freedom in grip style — claw and fingertip grips work particularly well. Gamers with larger hands (over 18 cm from wrist to middle fingertip) might find the mouse slightly small, so trying it in person is recommended if possible. * Budget-conscious gamers: At around ¥5,000, the XM1r delivers a premium sensor and durable switches without the premium price tag. It's an excellent entry point for anyone building their first gaming setup. That said, if wireless freedom or customizable RGB lighting is a priority, this wired, no-frills mouse will feel limiting.

Things to Consider

The XM1r is wired only. If you prioritize a clean, cable-free desk or need the flexibility of wireless, look elsewhere. The symmetrical shape is optimized for right-handed use — left-handed users will find the side buttons on the wrong side. Endgame Gear does offer a dedicated left-handed edition (XM1r Left-Handed Edition) for those who need it. The configuration software is available from the official website but is not localized in Japanese. Basic CPI and polling rate adjustments can be made via the button on the bottom of the mouse, so software isn't strictly necessary for everyday use. For advanced profile management, however, you'll need to navigate the English interface. Direct competitors in the same price bracket include the Razer Viper Mini (~61g, wired) and Cooler Master MM710 (~53g, wired). The XM1r differentiates itself with higher switch durability (80M clicks vs. 60M on many rivals) and a more refined click feel, though it offers fewer total buttons (6 vs. 6-7 on competitors).
