Keychron C1 Pro 8K

The C1 Pro 8K keeps the retro C1 look and adds 8000Hz polling. Keychron's page lists a plastic tray-mount body, Super switches (Red, Brown or Banana), OSA-profile double-shot PBT keycaps, Launcher remapping and 830 g. Tom's Guide called it extremely comfortable to type on, praising the OSA keycaps and the retractable feet, and the typing smooth and light, but found the Super switches tricky to remove and disliked that it is wired only. Notebookcheck described a matte plastic case that feels better than its class, clean stabilizers, smooth linear Super Red switches with a 45 gf actuation force, no chatter or repeat inputs, and flawless 8K polling, but noted the tray mount feels stiffer than a gasket design and it had trouble updating firmware. It also noted the keycaps are not shine-through.

Versions: this page also covers the C1 and C1 Pro, Keychron's earlier wired TKLs on the same retro plastic tray-mount design. Per Keychron's pages, the original C1 polls at 1000 Hz with no QMK/VIA or software, uses Gateron G Pro or Keychron mechanical switches with optional hot-swap and double-shot ABS keycaps, and weighs about 685 g. The C1 Pro adds QMK/VIA with the Launcher, K Pro switches and OEM-profile double-shot PBT keycaps at 1000 Hz and 700 g. The C1 Pro 8K moves to 8000 Hz polling, Super or Apex switches and OSA-profile keycaps.
