Our Verdict

Logitech Pebble Keys 2 K380s

Logitech Signature Slim Keyboard K950

The Logitech Pebble Keys 2 K380s and the Logitech Signature Slim Keyboard K950 are wireless, low-profile keyboards with replaceable AAA batteries. The Pebble Keys 2 K380s is significantly smaller, with a compact (75%) layout, making it a much better option for mobile or tablet use on the go. It has a more cramped layout that may take some getting used to. Comparatively, the Signature Slim Keyboard K950 has a standard full-size layout with standard spacing, making it the more comfortable option for a desktop setup and for typing for longer periods.
