Our Verdict

Logitech Pebble Keys 2 K380s

Keychron B33/B36

The Logitech Pebble Keys 2 K380s and the Keychron B33 are compact, low-profile wireless keyboards designed for everyday use. The Keychron supports wired, Bluetooth, and 2.4GHz connections, and it delivers much better raw performance in wired mode, which makes it suitable for gaming. Its keystrokes are noticeably deeper, which some users may prefer, and it comes with an internal rechargeable battery. It's also offered in a full-size B36 variant. In comparison, the Logitech is far more portable due to its slimmer design and lighter weight. The Logitech also relies on AA batteries instead of an internal rechargeable option.
