Alice Ergonomic Layout
A full-featured ergonomic office keyboard without the bulk of a traditional full-size keyboard. Its Alice layout reduces reaching and twisting, helping keep your fingers, wrists, and shoulders in a more natural position for comfortable, effortless typing throughout the workday.
SPACE EFFICIENCY
96% Layout — Dedicated Numpad
A near-full-size layout with a dedicated numeric keypad, providing a familiar typing experience with all the essential keys you need. The 96% layout keeps the functionality of a full-size keyboard while offering a clean, streamlined arrangement.
CONNECTIVITY
Tri-Mode Connectivity
Enjoy excellent performance with the B39's 2.4 GHz wireless connection, featuring a swift 1000 Hz polling rate for a cable-free and tidy setup. Effortlessly switch between devices using Bluetooth 5.2, enabling smooth multitasking. Wired (USB-C) – for a stable, plug-and-play connection and charging at the same time.
Productivity
M1-M5 Macro Keys
Five dedicated macro keys (M1-M5) let you assign custom shortcuts, text snippets, app launches, or complex command sequences. Configure them easily via the Keychron Launcher to automate repetitive tasks and boost your daily workflow.
TYPING EXPERIENCE
Quiet, Comfortable Typing
The B39 scissor-switch keys feature an extended key travel for a more substantial typing feel. Each keystroke remains stable and responsive, with the refined low-noise feedback you'd expect from precision scissor-switches — giving you the comfort of a mechanical-like experience in a sleek, quiet package.
Long-Lasting Power
500 Hours of Battery Life
The B39 comes with an 800 mAh battery, delivering up to 500 hours of battery life in 2.4 GHz wireless mode. Charge via USB-C and stay productive without worrying about frequent recharging.
