Keychron C3 Pro 8K Red Switch (C3PX-H1)

Wired Mechanical Gaming Keyboard in TKL (80%) format with a polling rate of 8000 Hz — a feature that was until recently found predominantly in magnetic models, now implemented with classic mechanical switches. With such a frequency, the input lag is just 0.125 ms, and via the Keychron Launcher web application, you can switch between the 1000, 4000, and 8000 Hz modes depending on your task.

The switches are proprietary linear Keychron Super Red, pre-lubricated, with a lifespan of up to 50 million keystrokes. Inside the case is a multi-layered noise isolation system: 3.5 mm thick EVA acoustic foam, IXPE film, EPDM gasket, and a silicone mat together form a muted dull sound of keystrokes. The board uses a Gasket Mount structure. The keyboard keycaps Keychron C3 Pro 8K Red Switch are made in Cherry profile using double-shot PBT plastic with translucent symbols.

The case tilt angle is adjustable in three positions (4°, 6°, and 8.7°). The firmware is based on the open platform QMK — key remapping, macros, and separate layouts for macOS and Windows can be configured through the Keychron Launcher directly in the browser. The switches support hot swapping and are compatible with most 3- and 5-pin MX switches. Connection is via a detachable USB-C cable.
