What’s New With The MX Master 3S?

If you currently own the Logitech MX Master 3, you’re wondering what is new or different with the Logitech MX Master 3S version. There are two main changes. The first change is an upgrade to an 8000 DPI sensor on the MX 3S versus the 4000 DPI sensor found on the MX 3. The second change is that the MX Master 3S has 90% quieter clicks than the MX Master 3. The quietness of the clicks is very similar to the amount of click noise on the new Logitech Vertical Lift mouse.

Oh, the MX 3S also comes in a pale grey version to match white setups. I’ll get into the 90% quieter clicks below and if it’s an improvement or a detriment.

What Hasn’t Changed?

These elements below remain unchanged on MX Master 3S when compared to the MX Master 3:

  • Still a 125 Hz Polling Rate
  • Same rubberized exterior material
  • No left-handed version available (Why Logitech? The Lift mouse has a left-handed version)

Price

The Logitech MX Master 3S mouse is $99.99 USD on Logitech’s website at the time of writing. The MX 3S comes in three colors, pale grey, graphite and black. I ordered the pale grey version.

In The Box

The package contains the mouse, Logi Bolt USB Receiver and manuals, and a USB Type C to Type A charging cable.

Design & Build Quality

If you’re familiar with the MX Master 3, please feel free to skip ahead because the exterior design remains unchanged.

The build quality is great, just like with the MX Master 3. In fact, the MX Master 3S has the same weight and dimensions as the MX Master 3. The mouse does not creak or wobble when moving it around.

The back of the mouse has a slick-looking silvery lip, which contrasts nicely against the pale grey. The silvery finish continues to the bottom of the mouse. The bottom of the mouse contains the power switch, sensor and a button to quickly switch between three different devices and to put the mouse in pairing mode for Bluetooth.

The front of the MX 3S contains the USB Type C charging port, which is convenient because the mouse can be charged during use.

The side of the 3S contains the horizontal scroll wheel, which comes in super handy browsing lots of data, or with timeline editing software. There is also a small button at the very bottom, under the backward and forward buttons, which can switch apps or be remapped to launch a specific app, open the start menu, etc.

Ergonomics & Hand Feel

The back of the mouse has a curved hump that nicely conforms to my hand without leaving any gaps, so it should accommodate most people’s hands easily. It feels quite planted even when moving it quickly in any direction. As there is no change from the MX 3, you will feel right at home with the MX 3S.

Buttons & Elements

The MX Master 3S has 7 buttons:

  • Right click & Left click
  • Backward & Forwards button
  • App Switch Button
  • Top Scroll Wheel Middle Click
  • Wheel Scroll Mode Button

90% Quieter Clicks? Yes, the claim is true. If you value quiet, the reduction in click noise may justify the cost of an upgrade to the MX 3S. I have gotten used to the quiet and soft clicks of the Logitech Lift Vertical mouse, and the MX 3S feels very similar in terms of the click noise. The clicks also feel a little softer too, but it is still tactile, so you know you are clicking the button. The quieter click only applies to the primary left and right-click buttons and no other buttons.

With seven mappable buttons, this mouse is excellent for general use or productivity workflows. All buttons are nicely laid out with easy access. One small change I noticed is that the side scroll wheel on the MX 3S feels slightly stiffer. I think this change was made to prevent accidental scrolling, but I never had this issue with the MX Master 3.

Probably the best feature of the MX 3 series is the MagSpeed Scroll wheel. This isn’t a marketing feature that will go unused. Once you use it, it will be hard to use other mice without this feature. If you’re not familiar with it, the top scroll wheel can be set to scroll fluidly at up to 1000 lines per second or set to scroll in increments like with traditional mice.

Connectivity & Multi-Device Options

Pairing is easily accomplished by Bluetooth or with the included Logi Bolt USB receiver. I use Bluetooth without issues because I like to keep the ever decreasing amount of USB ports on new devices empty. Logitech notified me that using the Logi Bolt USB Receiver provides the best results in terms of connectivity and latency.

Like the MX Master 3, the MX 3S can be paired with up to 3 devices to make use of Logitech’s Flow functionality, which allows for copying and pasting between different devices seamlessly. This must be set up in Logitech’s Logi Options+ software. Once set up, a quick switch button located at the bottom of the mouse is used to switch between different devices.

Upgraded Tracking

With an upgraded 8000 DPI sensor, Logitech mentions tracking works on virtually any surface, even glass. I tested the MX 3S on a glass pane with a black backdrop. While the MX 3S worked, it wasn’t a fluid experience, but it did do much better than the MX 3 did. However, if you don’t plan on using the mouse on glass, then the tracking on the MX Master 3 is perfectly capable and does not warrant the upgrade.

Mouse Settings & Customization

If you’ve used Logitech’s Options+ software before, you can expect all the same settings you’re used to. If you’re new to Logi Options+, it is a MUST to make the most out of your Logitech mouse and keyboard. I have screen-capped some of the options available when remapping buttons. There are more remapping options available when you scroll down (not pictured).

General Use & Performance

The MX 3S performs with the same excellence as the MX 3 for general or productive use. Logitech’s Options+ software also includes pre-set button configurations for popular software, such as Excel, Photoshop, browsers, etc.

I haven’t experienced any signal issues or disconnects when using the 3S. If you experience any of these issues when using Bluetooth, ensure that your computer is not set to turn off Bluetooth for power-saving in Windows.

Can I Recommend It?

If this is your first Logitech MX series of mouse, this is a great option, especially if you value quiet clicks.

If you own the MX Master 3, I can’t see any reason to upgrade to the MX 3S unless you really value quiet clicks. I do value quiet clicks, so I ordered it. You may also be interested in the 3S for the pale grey version if your plan is to match the rest of your white working setup. Keep in mind that it isn’t a pure white mouse. It’s an off-white color.

Here’s a photo of how the color of the pale grey compares to a standard piece of white printer paper and a PS5 Dual Sense controller.
