Endgame Gear OP1w 4k V2 Gaming Mouse - black

Introducing the OP1w 4k v2 - our most advanced wireless gaming mouse to date. Designed for peak competitive performance, it features our custom PixArt PAW3950 U+1F95A sensor engineered for unparalleled tracking accuracy and responsiveness. Powered by a Nordic wireless MCU, the OP1w 4k v2 delivers an ultra-fast 4000 Hz wireless polling rate for incredibly low click and movement latency.

Equipped with mechanical Kailh GX SPDT switches and compatibility with GX modes, the OP1w 4k v2 provides crisp, satisfying, and industry-leading fast clicks. Thanks to hot-swappable main switches, you can tailor the click feel precisely to your preferences. A new dust-protected Kailh encoder ensures smooth, consistent scroll performance with enhanced durability. As part of the OP1 series, the OP1w 4k v2 embodies the perfect fusion of cutting-edge wireless performance and customization.

Wireless Polling Rate up to 4000 Hz
For optimal performance, the OP1w 4k v2 is powered by the Nordic nRF52840 wireless MCU. The 4k dongle uses a Nordic nRF52820 to ensure stable and reliable wireless data transmission. Additionally, the dongle features a Nuvoton M483 MCU for high-speed USB connectivity, enabling high wireless polling rates up to 4000 Hz and delivering incredibly low sensor and click latency. The 4k dongle is included with the mouse, providing ideal performance right out of the box.

Custom PixArt PAW3950 U+1F95A
Experience ultimate precision and lightning-fast response times with our custom PixArt PAW3950 U+1F95A sensor in the OP1w 4k v2. With a maximum resolution of up to 30,000 CPI, 750 IPS, and 50 G acceleration, every movement is captured with absolute accuracy and maximum impact.

Also now available: an optional fixed sensor frame rate of 20,500 fps for even more responsive and precise tracking performance. Furthermore, the "Sensor Angle Tuning" feature allows adjustment of the tracking axis from -127 to +127 degrees in 1-degree increments for grip styles where the mouse is not held straight in the direction of movement, facilitating quick swipes and enemy tracking.*

Endgame Gear-Developed Kailh GX Switches
The mechanical Kailh GX switches are engineered for lightning-fast precision at all polling rates, ensuring you never miss a critical click. Their SPDT configuration guarantees optimal electrical contact and unmatched reliability. With contacts on both top and bottom, the Kailh GX switches excel whether you prefer low click latency in GX-Speed mode or security in GX-Safe mode. What sets them apart is their crisp, well-defined click feel, providing tactile feedback for enhanced gaming control. Precise actuation and balanced design ensure flawless, spam-friendly rapid-fire actions.

Industry-Leading Click Latency
The OP1w 4k v2 sets new standards for wireless device performance, boasting an average click latency under 310 microseconds*. With a constant 4000 Hz polling rate for clicks, you enjoy extremely low click latency across all sensor polling rate options. The GX-Speed mode further reduces click latency by about 1 ms. This exceptional responsiveness guarantees instant registration of every click, giving you an edge in critical gaming moments and helping you win game-deciding duels. But that’s not all. We’ve optimized movement latency to an average of under 400 microseconds**, delivering unmatched responsiveness. Initial movement latency from a standstill remains consistently fast across all polling rate options, further strengthening your in-game advantage.

Redesigned Shape for Versatile Claw Grip
The OP1w 4k v2 gaming mouse offers unparalleled comfort during intense gaming sessions, so you can fully focus on your performance. Inspired by the popular XM shape, the OP1 takes it a step further while maintaining a focus on the claw grip. Its flatter sides provide ultimate flexibility in finger placement, making it an excellent choice for gamers with larger hands as well. The extended sidewalls prevent accidental clicks, allowing you to rest your fingers on the edge without interruption. This subtle yet significant design change offers added comfort and control, catering to gamers with various hand sizes and grip styles.

Swappable Main Button Switches with Optional Switch Packs
What makes a great mouse click? Ask 10 people and you’ll get 11 different answers. Everyone has their own preferences, and sometimes we just want to use what no one else does. While the Kailh GX is a switch with an excellent combination of short internal travel, crisp actuation point, and high click frequency, you might still want to try your favorite switch. All OP1 mice feature a design with swappable main button switches and easily accessible screws on the bottom plate. This allows effortless customization and ensures the perfect click feel tailored to your taste. Choose from a variety of switch packs with different click feels and follow our simple step-by-step guide to swap the switches. With the universal switch pack, you can use any mechanical switch you can find—no soldering required.

Performance Comes First
We designed our wireless technology with performance as the top priority. By running the sensor permanently in "Corded Mode" and having the Nordic 58240 MCU perform only minimal power-saving measures, we ensure unmatched responsiveness for your gaming experience. To balance high performance with long battery life, the sensor defaults to power-saving mode after 1 minute of inactivity and deep sleep mode after 3 minutes. Users can easily adjust these settings to their gaming preferences and even disable power-saving and deep sleep modes entirely. With default settings, the OP1w 4k v2 offers approximately 30 hours of battery life for uninterrupted gaming at a 4000 Hz polling rate, enabling gamers to play continuously at peak performance.

Hybrid Skate Design
Much like click feel preferences, how a gaming mouse should glide is a science of its own and likely depends on the genre of games you play most. The OP1 features our so-called hybrid skate design. This means we’ve chosen a smaller skate set by default that offers an excellent balance between surface area, weight, and glide characteristics. Additionally, we include a larger skate set and a sensor skate, which is especially beneficial on softer mousepads. If you want to minimize the contact area of your mouse skates, for example, when using a glass mousepad, the large skate grooves of the OP1 offer numerous options to attach your preferred point skates. You can open the mouse via screws on the bottom plate and swap the main button switches without removing the skates. Thanks to improved adhesive on the v2 models, your skates can now be removed quickly and cleanly every time.
