Compare Keychron C4 HE vs K4 V2 Differences Side by Side

This comparison is for buyers deciding between two very different Keychron keyboards that share a brand but diverge in purpose. The C4 HE is a wired-only full-size keyboard built for low-latency gaming with 8000 Hz polling and magnetic Hall Effect switches. The K4 V2 is a wireless-oriented 96% model that prioritizes portability and multi-device connectivity via Bluetooth 5.1. The decision is hard because both offer hot-swappable switches and multimedia keys, but they target opposite priorities: raw speed versus flexibility.

Which Keyboard Is Better for Your Needs?

The C4 HE wins decisively for gaming and content creation due to its 8000 Hz polling and Hall Effect switches, and it also leads for modding thanks to its gasket mount and QMK/VIA support. The K4 V2 takes the office and travel categories with its Bluetooth 5.1 connectivity and large battery. For programming, they tie because both offer a number pad and hot-swappable switches without a clear advantage in firmware customization based on available data.
