Overview

  • 48.4g. Optimized lightweight. Refined with Fnatic pros.
    Refined to 48.4g (approx.) based on pro feedback, INZONE Mouse-A helps reduce fatigue and sharpen control over extended play. Its polyamide frame, engineered with hollow glass microspheres to reduce weight, delivers a stable feel with minimal flex.
  • Form for the grip of the game
    Shaped with the insight of Fnatic’s elite players, INZONE Mouse-A is built for optimal control and stability. Its contoured design supports high-speed maneuvers and repeat clicks, empowering focused play and minimal strain across competitive sessions.
  • 3950IZ sensor. Fast, precise, relentless.
    Our custom 3950IZ sensor delivers up to 30,000 dots-per-inch (DPI) of tracking resolution, dramatic linear accelerations with up to 70G of force, and 750 inches-per-second (IPS) imaging for wide sweeps and pinpoint accuracy even at elite-level speeds.
  • 8000Hz polling for ultra-fast input response
    INZONE Mouse-A supports custom polling from 500 to 8000Hz, communicating via its USB dongle for stable, low-latency performance. High-speed transmission reduces input lag and enables sharper tracking—fine-tuned for peak control in competitive play.
  • Stable 8000Hz performance with INZONE tuning
    The 3950IZ sensor delivers steadier 8000Hz polling over time, unlike other leading competitors—such as X and Y in the comparison table—which show sharp drops mid-game. INZONE holds strong, session after session.
  • Light-speed clicks with optical switch
    The optical switch reacts on light, not friction—delivering faster input and smoother keystrokes. Built for long-term reliability, it offers precise, consistent control from the first press to the final round.
  • Wheel
    Designed with Fnatic pros, the scroll wheel delivers tactile feedback on every notch, so you feel each scroll and stay in rhythm with play.
  • Side button
    Built with a reinforced design, the side button resists unwanted flex, staying solid under pressure even with firm clicks.
  • Back button
    The back button toggles power with a long press, or cycles through up to four customisable profiles. Versatile control, all in one.
  • Fast-charging, up to 90-hour battery life
    Please update battery life bullet to say: With up to 90 hours of use and a 5-minute quick charge delivers up to an extra 10 hours for play, the INZONE Mouse-A keeps you in the game longer
  • Fine-tune with the INZONE Hub
    The INZONE Hub puts full customization at your fingertips. Adjust DPI, polling rate, button functions, and more—then save it all to game-specific profiles for quick access. Available in both software and web versions.

Best Mouse I’ve personally used - Super lightweight and extremely precise with a simple to use and straightforward computer software for customization. No RGB on unit which for my setup is very clean. Build quality is great and battery life is superb

AdelMar 22, 2026 · Verified purchase ★★★★☆

perfect and comfortable medium gaming mouse! - this mouse feels and performs really good! I think it's a medium size very close to Pulsar X2 size 2. 8000 hz dongle included. the only con is it's a fingerprint magnet, and I don't like adding stickers

Great mouse, good battery life, good feel. best mouse i've used so far the price is the only weak point.

The Last Mouse You'll Ever Need - The Sony INZONE Mouse-A is hands down the best gaming mouse if not one of the best mice I've ever used. Super lightweight, amazing stock PTFE skates for silky smooth glide (especially on glass pads) and the raised back hump for increased stability makes this a solid choice for any serious gamer. The INZONE software is also pretty straightforward and intuitive. No bloatware compared to some other companies.
