Description
Kit at a glance
Logitech bundles the MX Keys S wireless keyboard with the MX Master 3S mouse so one desk setup covers fast typing and precise pointing. Link through Bluetooth Low Energy or the included Logi Bolt USB receiver on Windows, macOS, Linux, iOS, and Android.
Typing on the MX Keys S
Perfect Stroke keys use a low, laptop-like deck with spherically dished caps shaped to fingertips for quiet, accurate strokes. Backlighting wakes as your hands approach and reacts to ambient light; additional lighting tweaks live in Logi Options+. Programmable keys and Smart Actions in Logi Options+ let you fire multi-step workflows from a single keystroke and share those shortcuts with teammates. The chassis sits at an angle tuned for stability during long typing blocks.
Pointing with the MX Master 3S
The MagSpeed wheel—among Logitech’s fastest and most precise scroll mechanisms—can move up to 1,000 lines per second. An 8K DPI sensor keeps the cursor steady even on glass. The sculpted shell is shaped to reduce wrist strain across extended sessions.
Three devices, one button press
Pair each peripheral with as many as three devices and hop between desktop, tablet, or phone using dedicated switch controls—no full re-pair each time you change screens.

Where it fits
The pair targets productivity and office workflows. Responsive keys and accurate tracking also suit casual gaming; dedicated esports gear may still be preferable for competitive play.
