Our Verdict

The Logitech MX Master 3S builds on the excellence of its predecessor with meaningful upgrades like quieter clicks and a higher-resolution sensor. For professionals, content creators, and power users, this is simply the best wireless productivity mouse available today. Its ergonomic design, customizable controls, and ecosystem of features justify the premium price point for anyone who spends hours daily at their computer.

Design and Build Quality

The MX Master 3S maintains the iconic ergonomic shape that has made this series so popular, with subtle refinements that enhance the overall experience. Measuring 4.9 x 3.3 x 2.0 inches and weighing 5.0 ounces, it has substantial presence without feeling heavy. The mouse is designed exclusively for right-handed users with a contoured shape that perfectly cradles your palm.

The build quality is exceptional, with premium materials throughout. The main body features a matte finish with a soft-touch coating that provides excellent grip while resisting fingerprints. The scroll wheels are crafted from machined steel with a premium tactile feel that exudes quality.

Available in Graphite and Pale Gray color options, the MX Master 3S has a professional aesthetic that looks at home in any workspace. Logitech has paid attention to sustainability as well – the plastic parts contain 22% post-consumer recycled material, reflecting the company's commitment to reducing environmental impact.

Every curve and button is thoughtfully placed, making the mouse comfortable for extended use. The thumb rest provides an ergonomic resting position, while the button layout is intuitive and easily accessible without awkward finger gymnastics.

Performance and Features

The MX Master 3S introduces two significant improvements over its predecessor. First is the upgraded optical sensor, which now offers up to 8,000 DPI sensitivity (doubled from the previous 4,000 DPI). This higher resolution is especially beneficial for users with 4K or ultra-wide monitors, allowing for more precise cursor control across expansive screen real estate.

The second major upgrade is the new Quiet Click technology, which Logitech claims reduces click noise by 90% compared to the MX Master 3. In our testing, the difference is immediately noticeable – clicks remain tactile and satisfying but are dramatically quieter, making this an excellent choice for shared workspaces, noise-sensitive environments, or late-night work sessions.

The star feature remains the MagSpeed electromagnetic scroll wheel, which uses magnets to shift between two distinct scrolling modes: a precise ratchet mode with defined steps for detailed work, and a free-spin mode that allows the wheel to spin freely for up to 1,000 lines per second when navigating long documents or web pages. The wheel automatically switches between modes based on your scrolling speed (though this can be customized), providing an intuitive experience that adapts to your needs.

The secondary horizontal thumb wheel remains a productivity powerhouse, allowing for easy side-scrolling in wide documents or applications like timeline-based video editors. Combined with customizable thumb buttons and gesture controls, the MX Master 3S provides an unprecedented level of control and efficiency.

Tracking performance is flawless on virtually any surface, including glass (minimum 4mm thickness), thanks to Logitech's Darkfield sensor technology. Whether used on a traditional mousepad, desk surface, or even a glass table, the cursor movement remains precise and consistent.

Connectivity and Battery Life

The MX Master 3S offers multiple connectivity options to suit different setups and preferences. It can connect via Bluetooth Low Energy (no dongle required) or through Logitech's Logi Bolt USB receiver, which provides a more stable and secure connection. The Bolt receiver represents an upgrade from the older Unifying receiver, with improved security features and better performance in environments with lots of wireless devices.

One of the mouse's standout features is its ability to pair with up to three different devices simultaneously and switch between them at the touch of a button. This is perfect for users who work across multiple computers or want to control both a laptop and tablet. Logitech's Flow technology takes this even further, allowing you to move your cursor seamlessly between computers and even copy/paste files across devices.

Battery life is exceptional, with up to 70 days of use on a full charge. When you do need to recharge, the USB-C port delivers quick charging capabilities – just one minute of charge provides enough power for three hours of use. This effectively eliminates any concerns about battery anxiety during critical work sessions.

The battery status is clearly indicated via an LED on the mouse, and the Logi Options+ software provides more detailed information about remaining charge. In our testing, the battery performance aligned perfectly with Logitech's claims, making this one of the most reliable wireless mice available.

Software and Customization

The full potential of the MX Master 3S is unlocked through Logitech's Options+ software, available for both Windows and macOS. This intuitive application allows for extensive customization of button functions, scroll wheel behavior, pointer speed, and more.

What sets Options+ apart from basic mouse configuration tools is its support for app-specific customizations. You can create unique profiles for different applications, allowing the same physical button to perform different actions depending on which program you're using. For example, the thumb buttons could control zoom in Photoshop, navigate between tabs in your browser, and adjust volume in Spotify.

The software also enables gesture controls, activated by holding the gesture button on the thumb rest and moving the mouse. These gestures can be configured to trigger a variety of actions, from switching virtual desktops to controlling media playback.

For precision work, the DPI sensitivity can be adjusted in increments of 50 DPI, from 200 to 8,000 DPI. You can also set up to three different sensitivity presets and switch between them as needed for different tasks.

Options+ streamlines the setup process for Logitech Flow, which allows the cursor to move seamlessly between multiple computers as if they were a single workspace. This feature is particularly valuable for users who work across multiple devices, allowing for easy file transfers and shared clipboard content between computers.
