Compare Keychron C2 vs C4 HE Differences Side by Side

This comparison is for buyers seeking a full-size, wired keyboard for work or play. Both keyboards are wired-only, 100% ANSI layout boards from Keychron, but they target very different audiences. The C2 is an established, affordable option with standard mechanical switches, while the C4 HE is a newer, premium model featuring Hall Effect magnetic switches and an 8000 Hz polling rate. The difficulty lies in balancing the C4 HE's advanced performance features against the C2's proven track record and likely lower price point.
