When it comes to computer mice for productivity work, the MX Master series has been a popular choice for years. Logitech has now revealed the latest version, the MX Master 4, with even more features packed into the same ergonomic design.
The new MX Master 4 has mostly the same design as the previous MX Master 3, which is probably a good thing—no need to break what isn’t broken, after all. It still has an ergonomic profile designed for right-handed use, with a thumb rest on the left side. You left-handed folks will have to get a different mouse, like the Logitech Lift Left.
The main upgrade here is customizable haptic feedback, which gives you subtle vibrations for scrolling, navigation, and selection. It sounds a lot like the haptic features used in the Nintendo Switch 2, Apple Watch, and other similar devices, and Logitech says it’s “ideal for tasks like video editing, design work and data analysis.”
The two mouse wheels are still present, and there’s still a USB Type-C port for charging the internal battery, which provides “up to 70 days of power on a full charge and three hours of use from a one-minute quick charge.” You can save three paired devices at once, and switch between them with a button on the bottom, just like most other Logitech wireless accessories.
The MX Master 4 supports both Bluetooth Low Energy and the Logi Bolt USB receiver. That means you can use it as a regular Bluetooth mouse with most computers, tablets, and phones, while also having the option for a USB connection if needed. That might be helpful for desktops without Bluetooth support, or if you want to keep your mouse and other accessories on a KVM or other USB switch. The Bolt adapter is included with the mouse, and it’s a USB-C version.
As for internal hardware, Logitech says the MX Master 4 has “2X stronger connectivity” with a new chipset and optimized antenna placement. The main sensor is 8,000 DPI, just like the previous MX Master 3S.
Overall, the new MX Master 4 looks like a solid option for a desktop mouse, though PC gamers might still want a wired option for the lowest possible latency. I’m sticking to my Logitech Lift vertical mouse, but I did use an MX Master before that, and it worked well for several years.
The MX Master will be available in October 2025 for a price of $120. That’s a bit more expensive than the $100 launch price for the previous MX Master 3S, but that mouse quietly jumped up to $120 earlier this year. You’ll be able to buy it from Logitech’s online store and third-party retailers.
