Endgame Gear OP1w 4k Wireless Gaming Mouse

Built for Competitive Play 

While the outer shape remained identical to the famous OP1 shape, the inside was re-designed to achieve a lower overall weight of ~62g while maintaining a robust shell design without holes. The OP1w 4k has been developed by esports veterans for use in competitive play, with top-of-the-line components including PixArt's PAW3395 sensor, the Nordic nRF52840 wireless MCU, and Endgame Gear's exclusive Kailh GX SPDT switches with GX Mode compatibility.

Wireless Polling Rate of up to 4000Hz - Dongle Included! 

To achieve the best performance possible, OP1w 4k is powered by the Nordic nRF52840 wireless MCU. The 4k dongle utilizes a Nordic nRF52820 to guarantee stable and reliable wireless data transmissions. Additionally, a Nuvoton M483 MCU is used for the high-speed USB connection, enabling high wireless polling rates of up to 4000Hz for incredibly low sensor and click latency. The 4k dongle is included with the mouse for ideal performance straight out of the box.

While the Kailh GX is a switch with a very good combination of short internal travel, crisp actuation point and spammability, you may still want to try your favourite switch. All OP1 mice have a swappable main button switch design with accessible screws at the bottom plate. This allows for effortless customization, giving you the perfect click feel tailored to your liking. Choose from a variety of switch packs offering different click sensations, and follow our simple step-by-step guide to replace the switches. With the universal switch pack, you can use any mechanical switch you can find, solder-free. 

Industry-Leading Click Latency

The OP1w 4k sets a new standard for wireless performance with click latency measuring an average below 310 microseconds*. With a constant 4000 Hz polling rate for the clicks, you’ll experience ultra-low click latency, no matter which sensor polling rate you choose. This exceptional responsiveness ensures your every click is registered instantly, giving you a competitive edge and winning you the deciding duels.

PixArt 3395 Sensor

The OP1w 4k's responsiveness significantly improves by implementing the PixArt PAW3395 featuring a higher resolution pixel array and up to 26000 CPI, Lift-Off-Distance as low as 1mm, and up to 650 IPS for best accuracy during the fastest of swipes. The PAW3395 also offers sensor-level MotionSync for consistent and synced reports. With all smoothing and angle-snapping disabled, the tracking data from the sensor is as raw as it can be. Power-saving features are completely disabled (corded mode) squeezing every last bit of performance out of the OP1w 4k.

Kailh GX Switches developed by Endgame Gear

Designed for lightning-fast precision at all polling rates, the mechanical Kailh GX switches guarantee you won't miss a crucial click. Their SPDT configuration ensures optimal electrical contact and unmatched reliability. Featuring both top and bottom contacts, 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, defined click sensation, offering tactile feedback for enhanced gaming control. Precise actuation and a balanced design ensure flawless, spam-friendly rapid-fire actions.

Hybrid Skate Design

The OP1w 4k comes with two sets of PTFE skates (large & small) and a sensor skate. Thanks to a hybrid design bottom shell, it's possible to easily install either large or small skates with the smaller skates fitted by default. The larger area offers added flexibility when customizing the OP1w 4k's glide and re-using already purchased skates. The sensor skate is optional but recommended on softer surfaces.

(Almost) No Power-Saving

Engineered for peak performance the moment you plug it in, OP1w 4k ensures every click and movement is delivered with precision and speed. While the focus is on performance, Endgame Gear has also integrated customizable power settings for those who want to extend their battery life. Fine-tune your experience with adjustable sensor power-saving options and customizable deep sleep timers, giving you more control without sacrificing performance.
