Keychron has announced two new low-profile wireless keyboards, the K3 HE and K3 Ultra, both set to launch on February 12. The pair builds on the company's recent HE and Ultra designs, combining a slim form factor with gaming-focused features and wood accent details. Similar to the K2 HE , the upcoming K3 HE keyboard uses Lime low-profile hall effect magnetic switches, so users will be able to adjust actuation points, trigger and reset behavior, and configure multi-action or analog inputs. The Keychron K3 HE is also expected to support third-party low-profile Hall effect switches, including Gateron Magnetic Jade Pro and TTC KOM, avoiding a fully proprietary ecosystem. By contrast, the K3 Ultra sticks with traditional mechanical switches, using pre-lubed low-profile Milk POM switches with a high 8,000 Hz polling rate. This puts input latency as low as 0.125 ms, targeting competitive gaming scenarios where response time is a priority. The keyboard runs on ZMK firmware and is rated for up to 550 hours of battery life in 2.4 GHz wireless mode.

Both models emphasize portability and are expected to use an ABS bottom case with metal and wood frame similar to earlier HE Special Edition keyboards. The keyboards will be available in black and white versions. Keychron has not yet disclosed final pricing, though early access requires a $3 reservation fee.
