The Keychron J4 HE is an 80% TKL wireless keyboard with magnetic switches, adjustable actuation, and built-in Rapid Trigger for faster, more precise, and misfire-free keystrokes. It connects via 2.4 GHz, Bluetooth 5.2, or USB-C, with 1000 Hz polling over 2.4 GHz, and lets you remap keys, actuation, and RGB in your browser through Keychron Launcher. Hot-swappable and Mac/Windows-ready with onboard storage, it only takes one setup in the Keychron J4 HE User Guide to become the keyboard that fits you best.
