Keychron Q11 Ultra 8K Wireless Split Mechanical Keyboard

Ergonomic Computing, Programming, Typing, Productivity, Office Work, Custom Mechanical Keyboard Enthusiast

Overview

The Keychron Q11 Ultra 8K is a fully split 75% mechanical keyboard that cuts the cable between its two halves: each CNC-machined aluminium half talks to the other over 2.4 GHz, so you can place them at shoulder width without a bridge wire. It pairs an 8000 Hz polling rate and Bluetooth 5.3 with a 4000 mAh battery rated for up to 160 hours, while the gasket-mounted PC plate, hot-swappable Silk POM switches and double-shot KSA PBT keycaps deliver a premium, quiet typing feel. Open-source ZMK firmware and the browser-based Keychron Launcher handle remapping, macros and layers on macOS, Windows and Linux.

Key Highlights

  • True split 75% layout with 89 keys, two rotary knobs and a 5-key macro column — the two CNC-machined aluminium halves sync over 2.4 GHz, so no bridge or tethering cable is needed between them
  • 8000 Hz polling rate on 2.4 GHz and USB-C wired, with Bluetooth 5.3 for up to three devices; a 4000 mAh battery is rated for up to 160 hours with the backlight off
  • Full-metal CNC aluminium body with gasket mount and PC plate, hot-swappable Keychron Silk POM switches (Red linear / Brown tactile / Banana tactile) and pre-lubed screw-in stabilisers
  • KSA profile double-shot PBT keycaps with extra Mac and Windows modifiers in the box, adjustable typing angle via magnetic feet, and per-key RGB you can remap in the browser
  • Runs open-source ZMK firmware configured through the Keychron Launcher web app — per-key remapping, layers, macros and the built-in AI launcher with no software install
  • Available in Carbon Black and White (white colourway added November 2026), priced at $239.99 fully assembled
