Logitech MX Master 3S Wireless Mouse Ultra-Fast Scrolling, Ergo, 8K DPI, Track on Glass, Quiet Clicks, USB-C, Bluetooth - Graphite

The Logitech MX Master 3S is the definitive performance wireless mouse for professionals, creators, and power users — the iconic MX Master lineage remastered with Quiet Clicks, an 8,000 DPI Darkfield track-on-glass sensor, a remarkably quiet MagSpeed electromagnetic scroll wheel, USB-C charging with 1-minute quick charge, Easy-Switch 3-device connectivity, and 70-day battery life. For anyone who spends their working day in productivity applications, creative tools, or multi-device workflows — the MX Master 3S is the mouse that never needs to be replaced.

DARKFIELD HIGH PRECISION SENSOR — 8,000 DPI, TRACKS ON GLASS

The MX Master 3S is powered by Logitech's Darkfield High Precision Laser sensor — tracking accurately on virtually any surface, including glass (4mm minimum thickness). Standard optical sensors fail on glass entirely; the Darkfield laser's ability to track on glass makes the MX Master 3S usable on glass desks, glass conference tables, and glass studio surfaces where conventional mice cannot function. DPI is adjustable between 200 and 8,000 via Logi Options+ — covering the full range from slow, precise low-sensitivity work to fast cross-monitor navigation on large or multi-display setups.

QUIET CLICKS — 90% LESS NOISE, SAME TACTILE FEEL

Quiet Clicks deliver satisfying, soft tactile feedback with 90% less click noise compared to MX Master 3 — measured at 1 metre. The Quiet Clicks redesign preserves the full tactile click sensation — you feel every click clearly and register it accurately — while eliminating the audible impact that disturbs colleagues in open-plan offices, family members in shared spaces, and video call participants during live meetings. The MagSpeed scroll wheel is additionally near-silent in operation, making the entire MX Master 3S interaction almost acoustically imperceptible.

MAGSPEED ELECTROMAGNETIC SCROLL WHEEL — PRECISION TO 1,000 LINES/SEC

The MagSpeed electromagnetic scroll wheel is the defining feature of the MX Master 3 series — and the reason professional users choose it over every competing office mouse. MagSpeed uses electromagnetic induction rather than mechanical ratchet detents to control wheel movement:

- Precision mode: controlled, line-by-line scrolling with precise stopping for document editing, spreadsheet navigation, and code review

- Free-spin mode: a single flick of the wheel sends it spinning at up to 1,000 lines per second for instant traversal of long documents, web pages, and code files

- Auto-shift: MagSpeed automatically switches between precision and free-spin based on scroll speed — a fast flick activates free-spin; a slow scroll stays in precision mode

- Near-silent: the electromagnetic mechanism produces virtually no mechanical noise in either mode

The MagSpeed wheel is precise enough to stop on a single pixel and fast enough to scroll an entire 100-page document in under a second.

HORIZONTAL THUMB SCROLL WHEEL — NATURAL LATERAL NAVIGATION

A dedicated side thumb scroll wheel enables natural horizontal scrolling — navigating wide spreadsheets, panoramic timelines in video editing software, horizontal code layouts, and zoomed-in design canvases without requiring Shift+scroll or horizontal drag gestures. The thumb wheel's position follows the natural downward movement of the thumb for fluid, intuitive lateral navigation.

EASY-SWITCH — 3 DEVICES, ONE BUTTON

Easy-Switch enables seamless wireless switching between up to three paired devices — a desktop PC, a laptop, and a tablet, for example — with a single press of the dedicated Easy-Switch button on the mouse's base. Switch between devices in one second without re-pairing, without opening software, and without removing the receiver from any device. For users who work across multiple computers throughout the day, Easy-Switch eliminates the need for multiple mice or constant Bluetooth re-pairing.

7 PROGRAMMABLE BUTTONS — LOGI OPTIONS+ CUSTOMISATION

All 7 buttons on the MX Master 3S are fully remappable via Logi Options+ (Windows and macOS):

- Primary L/R click: standard click — remappable

- 2x thumb buttons: Back/Forward by default — remappable to any shortcut, macro, or function

- Gesture button: hold + directional movement triggers custom gesture commands per application

- Side scroll click: middle-click by default — remappable

- Scroll wheel click: middle-click — remappable

Application-specific profiles automatically activate the appropriate button configuration when switching between applications — the same gesture button can execute a different command in Premiere Pro vs Excel vs Chrome, without manual profile switching.

LOGI BOLT + BLUETOOTH — DUAL WIRELESS CONNECTIVITY

- Logi Bolt USB-A receiver: encrypted 2.4GHz connection for maximum reliability in RF-congested office environments — immune to the Bluetooth interference that affects open-office wireless keyboards and mice

- Bluetooth Low Energy: direct pairing to any Bluetooth-equipped device without occupying a USB port — ideal for tablets, laptops without USB-A, and secondary devices in an Easy-Switch setup

USB-C CHARGING — 70 DAYS + 1-MINUTE QUICK CHARGE

A full charge via USB-C provides up to 70 days of wireless use — covering more than two months of daily professional use between charges. The 1-minute quick charge feature provides 3 hours of use from a single minute of USB-C charging — eliminating the interruption of an unexpectedly depleted battery during a working day.

RIGHT-HAND ERGONOMIC — PALM REST, TILT ANGLE, THUMB REST

The MX Master 3S's sculpted ergonomic body is engineered for extended daily use:

- Natural tilt angle: positions the forearm and wrist in a more natural, less pronated posture — reducing the forearm rotation strain associated with flat mice during extended use

- Palm rest: the full mouse body supports the palm — distributing hand weight across the entire hand surface rather than concentrating pressure at the wrist

- Thumb rest: a dedicated textured thumb rest area supports the thumb without requiring active gripping

- Textured grip surfaces: rubberised grip areas on the sides and scroll wheel prevent slipping without requiring a firm grip

27% POST-CONSUMER RECYCLED PLASTIC

The Graphite MX Master 3S incorporates 27% certified post-consumer recycled plastic across its chassis components — reflecting Logitech's commitment to responsible material sourcing in its premium product lineup.
