Product Description

The Keychron M4 Mouse is a lightweight, compact option suited for users who prioritize portability and precision in a small form factor. It fits well for competitive FPS players or general users who want flexible connectivity and adjustable sensitivity without extra buttons or ergonomic features. Its minimal design favors fingertip or claw grip styles and smaller hands.

Sensor & Tracking

This mouse uses a PixArt PAW3395 sensor with DPI adjustable from 100 to 26,000, allowing precise control for various gaming or productivity needs. The polling rate is 1000 Hz in wired and 2.4 GHz modes, providing responsive tracking. Bluetooth mode lowers the polling rate to 125 Hz, which may reduce responsiveness for fast-paced gaming.

Connectivity

The Keychron M4 offers three connection methods: wired USB-C, Bluetooth 5.1, and 2.4 GHz wireless. Wired and 2.4 GHz modes support high polling rates suitable for gaming, while Bluetooth prioritizes convenience over speed. Included adapters and a USB receiver enhance compatibility. Battery capacity is 300 mAh, but exact runtime is unknown.

Shape & Ergonomics

With a total weight of 35 grams and a very small design, this mouse is easy to carry and maneuver quickly. It suits fingertip and claw grips best and smaller hands. The lightweight build reduces fatigue in short sessions but may feel less stable for users preferring heavier mice. Lift-off distance is adjustable between 1mm and 2mm, helping avoid unwanted cursor movement when repositioning.

Buttons & Switches

Main buttons use Huano micro switches, known for a tactile click feel. The mouse does not have extra programmable buttons, limiting customization for MMO or productivity users who need macros. Scroll wheel details are unknown.

Trade-offs

  • The small size and light weight may not suit users with larger hands or those who prefer palm grip comfort.
  • Bluetooth mode has lower polling rate, which can impact responsiveness in competitive gaming.
  • No information on software customization or onboard memory is available.
