Compare Keychron K4 Pro vs V6 Differences Side by Side

This comparison helps buyers choose between two QMK-programmable Keychron models that share many core features but differ in layout and connectivity. The K4 Pro brings a compact 96% layout with Bluetooth 5.1 for multi-device wireless use, while the V6 offers a traditional full-size 100% layout in a wired-only design with the option of a knob variant. The decision is difficult because both keyboards support hot-swappable switches, screw-in stabilizers, sound dampening, and full VIA/QMK customization, making the primary trade-off about whether you need wireless freedom or a dedicated navigation cluster and rotary encoder.

Pros and Trade-offs

If a clutter-free desk and the ability to switch between multiple devices wirelessly are important to you, the Keychron K4 Pro is the better choice with its Bluetooth 5.1, compact 96% layout, and large battery.

Both keyboards deliver strong QMK/VIA customization, hot-swappable switches, and solid build quality.
