DPI resolution

The Master 3S has a new 8K sensor. In doing this the Dots per inch (DPI) has been doubled relative to the MX Master 3. DPI is a measure of sensitivity. The higher the DPI, the more sensitive the mouse.

The question is

How many DPI do you really need?

High DPI would be an advantage to gamers on account of the precision. However, most gamers don’t use a DPI of higher than 2000. For gaming applications the comfort factor, lift-off distance, and sensor axis bias or acceleration are more important.

Click Volume

It looks like Logitech took customer feedback into account on certain negative attributes. One of them being the volume of the click. Many customers have complained about it being too loud. The MX Master 3s features Quiet Click buttons that Logitech claims will be 90% quieter than those in the MX Master 3.

Wireless Connectivity

The MX Master 3 featured two wireless connectivity methods – Unifying and Bluetooth. The 3s on the other hand features the new Bolt technology which is newer and more secure. We have discussed the differences between the Bolt and Unifying receivers in an earlier post.


The MX Master 3S is currently available at a discount relative to the MX Master 3.


Overall we feel that the updates could be classified as evolutionary as opposed to revolutionary. An immediate upgrade might not be worth it if you’ve got a working MX Master 3.

Although we anticipate Logitech will stop shipping the MX Master 3 in the near future.

As well the move to Logi Bolt technology confirms our earlier suspicions that Logitech will standardize on Bolt receiver technology for productivity applications.
