Xiaomi Wireless Mouse 4 Pro Goes on Sale July 7 for 199 Yuan

Xiaomi’s Wireless Mouse 4 Pro goes on sale in China on July 7 for 199 yuan (around $28). The new model comes with a TOG omni-channel sensor that tracks on glass surfaces at least 4mm thick, a dynamic electromagnetic scroll wheel, and support for connecting with three devices at the same time.

The TOG sensor allows the mouse to work on a wider range of surfaces than a standard optical sensor. According to Xiaomi, tracking remains stable even on glass desks without requiring a mouse pad. That makes it useful for offices, meeting rooms, and other workspaces where glass tabletops are common.

Instead of relying on a traditional mechanical scroll wheel, Xiaomi has fitted the Wireless Mouse 4 Pro with an electromagnetic wheel that changes its behavior automatically. Slow scrolling provides precise step-by-step movement for spreadsheets, documents, and detailed editing, while faster scrolling switches to a smooth free-spin mode for moving through long web pages, large PDF files, or lengthy reports.

The change is based on both scrolling speed and finger pressure, so users do not need to press an extra button to switch between the two modes.

The mouse supports one 2.4GHz wireless connection and two Bluetooth connections, allowing three devices to remain paired at the same time. Switching between a desktop, laptop, or tablet takes only a button press, making it easier for people who work across multiple devices during the day.

Xiaomi is replacing conventional desktop software with a web-based configuration platform. Supported settings can be adjusted directly through a web browser, eliminating the need to install a separate driver application before changing mouse settings.

The Wireless Mouse 4 Pro will be available in black and white. It measures 115.5 × 62 × 36.5 mm and weighs about 66 grams without the battery. Xiaomi lists the size for small to medium-sized hands, keeping the design compact without making it overly small.

A magnetic top cover provides access to the battery compartment and stores the 2.4GHz USB receiver inside the mouse when it is not connected to a computer. Keeping the receiver inside the body helps reduce the chance of losing it while carrying the mouse between different locations.

Sales begin in China on July 7 with a retail price of 199 yuan. Xiaomi has not shared pricing or availability for other markets.
