Meet the next-generation HERO 16K Sensor, our most advanced sensor ever, with 1:1 tracking, 400+ IPS, and 100-16,000 max DPI sensitivity — plus zero smoothing, filtering, or acceleration.
Game-driven, full-spectrum RGB lighting responds to in-game action, audio, and screen color, synchronizing across G gear. Customize lighting animations and effects from ~16.8M colors using G HUB gaming software, and personalize to match your rig.
G403 is lightweight and comfortably designed to mold to your hand with rubber grips for added control. An optional 10 g removable weight lets you tune the weight to your preferences.
Configure 6 programmable buttons using Logitech G HUB software to simplify in-game actions. Customize your DPI sensitivity setting from 100 - 16,000 DPI. Choose pixel-precise, low-sens targeting to lightning-fast maneuverability.
With a 1ms response time, G403 is up to 8x faster than standard mice not designed specifically for gaming, delivering near-instantaneous moves and clicks. G403 also features advanced metal-spring button tensioning, keeping the primary left and right mouse buttons poised to trigger with less force. That means exceptional button feel, response, and consistency with every click.
