Compare Keychron C4 HE vs K4 HE Differences Side by Side

This comparison is for buyers deciding between two Keychron magnetic switch keyboards: the wired C4 HE with an 8000Hz polling rate and the wireless K4 HE with a 1000Hz polling rate. The decision is difficult because both feature Hall Effect switches, PBT keycaps, and VIA support, but they target different priorities. The C4 HE emphasizes raw competitive speed and a full-size layout, while the K4 HE offers wireless connectivity and a smaller 96% form factor with aluminum or wood construction. Your choice hinges on whether you value minimum input lag or freedom from cables and a more premium build.
