The K3 HE introduces Keychron's first slim Hall Effect keyboard with adjustable actuation down to a jaw-dropping 0.1mm precision, while the K3 Ultra 8K delivers a true 8,000 Hz wireless polling rate in an ultra-slim 75% layout. Both models feature a gorgeous metal chassis with natural rosewood framing, hot-swappable switches, and LSA low-profile double-shot PBT keycaps. The attention to sound design is chef's-kiss-level, with noise-damping materials in the case and they even ship screwdrivers for modding.

Keychron keeps things clean with PBT keycaps (more durable and eco-friendlier than ABS), and the K3 Ultra's ZMK firmware enables an incredible 550-hour battery life, meaning far fewer charge cycles over its lifetime. Both models support Bluetooth, 2.4 GHz, and wired connectivity for maximum versatility and longevity. No flashy sustainability pledges here, but the build quality screams "buy it for life."

Early Bird pricing starts at just $105 for the K3 Ultra and $115 for the K3 HE. For keyboards packing Hall Effect magnetic switches or 8K Hz wireless polling, these prices are extremely competitive. Estimated shipping kicks off in May 2026, with ISO layouts following in July.
