I make no secret of the fact that I adore the MX Master 3. I called it “peerless” and that’s something that is still true today. But, three years is a long time in the tech world, so Logitech has gone and made it even better. Read our MX Master 3 Review.BY Kenny Yeo

The MX Master 3S is different in two key ways. The first is that it has quieter left and right mouse buttons. Logitech calls it Quiet Clicks and claims the new mouse buttons produce 90% less noise. I can’t confirm if the MX Master 3S is really 90% quieter but it is noticeably quieter than its predecessor.
Impressively, Logitech managed to dampen out almost all of the click noise without sacrificing much in the way of tactility. Often, quiet or silent versions of switches can feel mushy or vague and less tactile and precise, but the MX Master 3S retains almost all of the tactility of its noisier predecessor. Obviously, the mouse buttons feel softer and more damped, but it retains a pronounced point at which clicks register. To my fingers, the overall sensation is also more rounded – more Topre, less Cherry MX.
The other big change is the sensor. It’s now a higher resolution 8,000 DPI unit, which doubles its predecessor. Perhaps more crucially, it continues to work on various surfaces – I tested it on wood, glass, metal, and even fabric.
Logitech says the higher resolution sensor helps users who work with high-resolution displays, but I’m not sure that’s necessary. I’ve been using the MX Master 3 with a 4K monitor for the past two years and recently added the 5K Apple Studio Display to my setup, and not once have I felt that I needed a more sensitive sensor. For what it’s worth, I have the MX Master 3S set at 1,500 DPI while the tracking speed at the OS level is at the fourth highest setting.
Elsewhere, the MX Master 3S is identical to its predecessor. The highly sculpted shape is the same and so are the buttons. Apart from your usual left and right mouse buttons, there’s a vertical scroll wheel, a horizontal scroll wheel, a thumb button, back and front thumb buttons, and an additional button under the vertical scroll wheel. That’s a lot of buttons. It also comes in two colours – Graphite and Pale Gray – which is really just a fancy way of saying black and white.
The vertical scroll wheel is the same electromagnetic MagSpeed unit which uses magnets to switch between a freewheeling spin mode and a step-by-step ratchet mode. And, like its predecessor, the all of the mouse’s wheels and buttons are customisable through the Logi Options+ app (available for both Windows and Macs). The customisation options are powerful and detailed.
Battery life is unchanged at 70 days on a full charge. This sounds about right as I usually get close to two months of use from my MX Master 3. And if you ever find yourself completely out of juice, the mouse’s quick-charging feature lets you get three hours of use from just a single minute of charge. It charges over USB-C.
You can also pair with up to three devices either over Bluetooth or with the Logitech Logi Bolt USB receiver, but annoyingly, the button to switch between devices is still at the bottom of the mouse.
And because the MX Master 3S is mostly identical to its predecessor, the same problems remain. It is not suitable for left-handers, there’s no physical battery level indicator, and is quite heavy. At $ the MX Master 3S isn’t exactly what you’d call affordable, though it’s also not quite as pricey as some high-end gaming mice.
Should owners of the MX Master 3 run out to upgrade? I don’t think so, unless you absolutely must have a quieter mouse or you have hands so sensitive that it can maximise its new 8,000 DPI sensor. The only reason most other owners should upgrade is if their MX Master 3s have become badly worn from use.
If you have an older MX Master mouse or any other mouse, then it’s a no-brainer. The MX Master 3S is a fantastic mouse for productivity and general use. Its features, high level of customisation, and overall refinement are unmatched. If you spend a lot of time at your computer, this is an extremely worthy investment.
SMALL, BUT PROFOUND UPGRADES TO THE MX MASTER 3.
