Our take, based on research
A wired Hall-effect 75% on maker specs. Evidence for this exact model is Keychron's page; the only review found covers the wired J2 HE 8K sibling, so how this board feels is not independently documented.
Overview
The J8 HE 8K is a wired Hall-effect 75% with 8000Hz polling. Keychron's page lists hot-swap Keychron Ultra-fast Lime magnetic switches, Cherry-profile double-shot PBT keycaps with Mac and Windows sets, a plastic gasket-mount body, plate-mounted stabilizers, north-facing RGB, three feet angles (4, 8 and 10 degrees) and 956 g, working with Windows, macOS and Linux. It is wider (148 mm) and heavier than the J2 HE 8K (140 mm, 780 g). No independent review of the J8 turned up. GetGeek.ro's review of the J2 HE 8K found rapid trigger and adjustable actuation worked as expected, and a sturdy plastic case with a damped sound; that is the closest guide, not a test of this board.
