MX Series
Precision in Motion.
The MX Master 3S brings 8K DPI tracking, near-silent clicks and MagSpeed scrolling to your most demanding work anywhere, on any surface, even glass.
8KDPI
Track on glass. Track on anything.
A 200–8,000 DPI Darkfield high-precision sensor lets you work on any surface, including glass as thin as 4 mm. From CAD and pixel-level photo edits to spreadsheets the size of a building, the cursor goes exactly where you point.
1000lines/sec
Electromagnetic. Hyper-fast. Silent.
The MagSpeed wheel tears through 1,000 lines per second and is 90% faster, 87% more precise and 87% quieter than a standard wheel. SmartShift automatically switches between ratchet and free-spin depending on how hard you flick.
90% quieter
The feel you love. Without the noise.
Re-engineered switches deliver a 90% reduction in click sound while preserving the same satisfying tactile response. Click confidently in shared rooms, on calls, or in a quiet library.
7buttons
Sculpted to support your hand.
The signature MX silhouette puts your thumb in its natural resting position. A thumbwheel, gesture button, forward / back keys and customizable side buttons keep every shortcut a flick away.
70days
One full charge. Up to ten weeks of work.
A 500 mAh rechargeable Li-Po cell delivers up to 70 days on a single charge. A one-minute USB-C quick charge gives you three hours of use plug in only when you remember to.
3devices
One mouse. Three machines. Zero friction.
Pair MX Master 3S with up to three computers and switch between them with a tap. With Logi Flow, glide your cursor across screens and copy text, images and files between Windows and macOS as if they were one desktop.
∞per app
Customize every button. Per app.
Logi Options+ remaps every button and gesture, automatically tailoring them to the app you're in Figma, Zoom, Final Cut, VS Code, Photoshop and more. Smart Actions chain multi-step shortcuts into a single click.
