Pulsar X2

Overview

The Pulsar X2 series comprises wireless gaming mice engineered for competitive gameplay, with a specific emphasis on first-person shooter (FPS) titles. Introduced by Pulsar, a company founded in 2020, the X2 line distinguishes itself through its low mass and ambidextrous form factor. The design prioritizes ergonomic comfort for various grip styles, while maintaining a weight profile that facilitates rapid, high-precision movements required in competitive gaming scenarios. The standard X2 model targets users with medium-to-large hands, while the X2 Mini variant caters to users preferring a more compact chassis or having smaller hand sizes.

Each iteration within the X2 series integrates the PixArt PAW3395 optical sensor, a component recognized for its tracking accuracy and high maximum DPI (dots per inch) capabilities according to RTINGS.com's sensor performance tests. The wireless connectivity operates on a 2.4 GHz frequency, aiming to provide a low-latency connection comparable to wired alternatives. This is a critical factor for competitive players where input lag can affect reaction times as discussed by Tom's Hardware. The X2 series also features mechanical switches, typically Kailh GM 8.0s or Huano switches, chosen for their tactile feedback and durability.

Pulsar's approach with the X2 series focuses on delivering a performance-oriented peripheral without extraneous features that could add weight or complexity. The mice are designed to be plug-and-play compatible, with optional software for customization of DPI settings, polling rates, and button assignments. The minimal aesthetic and focus on core performance metrics position the X2 as a viable option for professional gamers and enthusiasts who prioritize speed, accuracy, and lightweight design in their gaming peripherals.

The product line has seen several iterations, including special editions featuring different colorways or minor component revisions, but the core design principles of lightness and wireless performance remain consistent across the series. The X2's ambidextrous shape, devoid of pronounced ergonomic curves, allows for flexibility in grip style, accommodating claw, fingertip, and palm grip users depending on hand size and specific model (standard or mini). This adaptability makes it suitable for a broad segment of the gaming community, particularly those seeking a versatile and high-performing wireless mouse.

Getting started

The Pulsar X2 mice are designed for immediate use upon connection. The following steps outline the typical setup process for optimal performance.

1. Unpack the Pulsar X2 mouse and its USB-C cable and 2.4 GHz wireless dongle.
2. For wireless operation, plug the 2.4 GHz wireless dongle into an available USB-A port on your computer.
3. Turn on the mouse using the power switch located on the underside of the mouse.
4. The mouse should automatically pair with the dongle. The DPI button on the underside can cycle through preset DPI stages.
5. (Optional) For advanced customization, download the Pulsar Fusion software from the Pulsar website's download page.
6. Install and launch the Pulsar Fusion software.
7. Within the software, you can adjust DPI settings, polling rate (e.g., 1000 Hz, 4000 Hz, 8000 Hz if supported by your model/dongle), button assignments, and macro settings.
8. Ensure the mouse firmware is up to date via the Fusion software for the latest performance enhancements and bug fixes.
9. For wired mode, connect the USB-C cable directly from the mouse to your computer. This also charges the mouse battery.
