What Makes the MX Master 3S Special?
The MX Master 3S isn’t just a mouse — it’s a precision engineering masterpiece designed for people who spend hours at a computer every day.
1. Quiet Clicks That Still Feel Satisfying
The headline upgrade over its predecessor is Quiet Clicks — 90% less click noise compared to the MX Master 3, yet the tactile feedback remains crisp and satisfying. If you work in open offices, cafes, or late at night, this alone makes the upgrade worthwhile.
2. 8,000 DPI Darkfield Sensor — Works on Glass
Most mice struggle on glass surfaces. The MX Master 3S uses Logitech’s Darkfield optical sensor with 8,000 DPI precision, tracking on virtually any surface including glass (minimum 4mm thickness). You can adjust sensitivity in Logi Options+ from 200 to 8,000 DPI — perfect for photo editing, coding, or casual browsing.
3. MagSpeed Electromagnetic Scroll Wheel
The MagSpeed scroll wheel scrolls 1,000 lines per second in free-spin mode — perfect for navigating long spreadsheets, code files, or web pages. It switches automatically between ratchet and free-spin modes based on speed, and the machined steel construction gives it premium tactility. Nearly silent, too.
4. Ergonomic Design Built for All-Day Use
Sculpted for right-handed users, the MX Master 3S supports the natural curve of your hand with a thumb rest, side scroll wheel, and perfectly placed customizable buttons. At 141g, it’s heavy enough to feel premium without causing strain during marathon work sessions.
5. Connect Up to 3 Devices Simultaneously
The Easy-Switch button lets you pair up to 3 computers and switch instantly. Combined with Logi Flow in Logi Options+, you can move your cursor straight from one computer to another — and even copy-paste across machines. Genuinely useful if you keep a laptop and a desktop on the same desk.
6. 70-Day Battery Life
USB-C charging delivers up to 70 days on a full charge. A 1-minute quick charge gives 3 hours of use — so you’re never truly stranded.

How long does a full charge take?
