Our Verdict

Keychron K2 (Version 2)

Keychron K3 (Version 2)

The Keychron K2 (Version 2) and the Keychron K3 (Version 2) are compact wireless keyboards that perform similarly. The major difference is that the K3 V2 is a low-profile board with low-profile switches with a much shorter pre-travel distance than the switches on the K2 V2. That said, the K3 V2 has better ergonomics because of its low profile, but the K2 V2 feels more like a traditional mechanical keyboard. Both keyboards come in hot-swappable variants, so you can swap the switches out without soldering.
