Xiaomi Wireless Mouse 4 Pro: an ergonomic novelty with a smart wheel for $30

Xiaomi has expanded its line of peripheral devices by announcing the Wireless Mouse 4 Pro wireless mouse. The novelty combines modern technological solutions, premium ergonomics and an affordable price.

Features of design and construction

Wireless Mouse 4 Pro is a compact wireless manipulator designed specifically for users with small or medium palm size. With dimensions of 115.5×62×36.5 mm, the mouse weighs only 66 grams without taking into account the power element.

The design of the case is thought out to the smallest detail: the top panel is held by magnets, providing quick access to the battery compartment and the USB receiver slot hidden inside. The base is equipped with wear-resistant Teflon feet (PTFE), which guarantee smooth sliding on any surface.

Technical characteristics and functionality

The main technical advantage of the mouse is the Xiaomi TOG (Track-On-Glass) sensor, which allows the device to maintain high accuracy even when working on glass surfaces with a thickness of 4 mm or more without the need to use a mat.

Another important feature was the “intelligent” scroll wheel with an electromagnetic mechanism. It automatically adapts to the speed of rotation: with slow scrolling, the user receives a classic step-by-step movement, and with sharp movement, the free rotation mode is activated, which is ideal for navigating voluminous documents.

Features of button operation

• Silent TTC switches: provide crisp response while keeping noise to a minimum.
• Metal side buttons: support software action reassignment.

Connection and configuration options

The mouse supports multi-channel connection, allowing you to work with three devices at the same time. One connection is made via the included 2.4 GHz USB receiver, and the other two via the Bluetooth 5.0 protocol. Quick switching between connected gadgets is implemented through a separate button on the case.

Ease of use is enhanced by the absence of the need to install drivers or other software: parameter management (assignment of buttons, switching DPI presets: 1000, 1600 and 2400) is available through the browser interface.

Price and release date

The Xiaomi Wireless Mouse 4 Pro will be available in black and white from July 7, 2026. The first sales region will be China, where the device is priced at $29 (about UAH 1,160). Information about global availability has not yet been announced.
