The Logitech MX Master 3 and Logitech MX Master 3S are two of the best productivity-focused wireless mice you can buy, beloved by professionals, creatives, and power users. While the original MX Master 3 laid the foundation with outstanding ergonomics and precision, the MX Master 3S refines that experience with quieter clicks, a higher-resolution sensor, and more modern connectivity — making it our recommended choice overall.
Choose the Logitech MX Master 3 — it remains an ergonomics and productivity powerhouse with lightning-fast MagSpeed scrolling, custom buttons, and multi-device support that millions trust daily. But if you want even quieter clicks and more precise tracking, the MX Master 3S is worth consideration too.
Why Do I Recommend Logitech MX Master 3S?
- Upgraded 8K Sensor for Smoother Precision: The MX Master 3S sports a new 8000 DPI optical sensor (compared with the MX Master 3’s 4000 DPI), offering more precise and responsive tracking — especially helpful on high-resolution displays and multi-monitor setups.
- Quieter Clicks for Office & Shared Workspaces: Logitech says the MX Master 3S features up to 90 % quieter left/right clicks than the original, making it perfect for distraction-free work at home, in open offices, or during meetings.
- MagSpeed Scrolling & Workflow Boosts: Both models include Logitech’s MagSpeed electromagnetic scroll wheel, which scrolls up to 1,000 lines per second and shifts between fast and precision modes seamlessly — a huge productivity gain for long documents and spreadsheets.
- Multi-Device & Flow Support: Switch effortlessly between up to three connected devices (Bluetooth or USB receiver) and use Logitech Flow to share clipboard content and files between machines — ideal for multi-device workflows.
