Xiaomi has put the Xiaomi Wireless Mouse 4 Pro on sale in China, and this one is trying to be more useful than exciting – which is exactly what most office mice should aim for. The Wireless Mouse 4 Pro costs 199 yuan and goes on sale on July 7, with a compact shell, silent switches, multi-device support, and a scroll wheel that switches behavior depending on how fast you flick it.
The pitch is familiar, but the execution is more thoughtful than the usual budget peripheral checklist. Silent switches, glass tracking, and a built-in receiver slot make it a practical option for people who jump between laptops, desktops, and tablets without wanting another desk accessory to babysit.
Wireless Mouse 4 Pro price and size
The mouse measures 115.5 by 62 by 36.5 mm and weighs 66 grams without a battery installed, so Xiaomi is clearly aiming at small to medium hands rather than the palm-filling crowd. It comes in black and white plastic, with a magnetic top cover that lifts off to expose the battery compartment and a storage slot for the included 2.4GHz USB receiver.
That design choice is practical, not glamorous, and that is the point. The underside uses standard PTFE feet, while the main buttons rely on TTC silent switches with longer key travel, a setup that should feel more deliberate than mushy in shared spaces.
How the scroll wheel works
The standout feature is the dynamic electromagnetic scroll mechanism. Move the wheel slowly and it behaves like a traditional notched wheel for line-by-line reading; flick it faster and it unlocks a free-spin mode for racing through long pages and documents.
That kind of dual-mode scrolling has been showing up in more premium mice for years, and it is smart to see Xiaomi borrowing the idea for a mainstream product. A good wheel is one of those things people forget to ask for until they use a bad one.
Connectivity, sensor, and controls
Inside, Xiaomi uses its TOG sensor, which can track on clear glass surfaces as long as the glass is at least 4 mm thick. That means the mouse should work on some desk surfaces without a pad, which is handy if your workspace looks like a design showroom and behaves like one too.
Connectivity covers up to three devices at once: one over the 2.4GHz USB receiver and two through Bluetooth 5.0. A dedicated button switches between them, while the side buttons can be remapped and a small LED on top shows battery life and DPI status.

Web-based settings instead of software bloat
Xiaomi also supports the mouse with a web-based driver, so users can adjust DPI, remap the side buttons, and tweak performance settings from a browser rather than installing dedicated software. That is a small but sensible move, especially for people who do not want yet another background app hanging around on work machines.
The bigger question is whether this sort of mouse can keep price-sensitive buyers from simply grabbing the cheapest wireless model available. If Xiaomi’s track record with everyday gadgets is any guide, the answer depends less on raw specs than on whether the scroll wheel and silent clicks feel better in hand than the spec sheet suggests.
