Manufacturer's published specifications.
Verdict: the little round-keyed board you’ve seen in a decade of desk photos, quietly refreshed. Nothing here chases specs — it’s thin, silent, pairs with three devices, and runs on AAAs for years, which is exactly why the K380 line keeps getting searched for while flashier boards come and go.
The specs that matter
Per Logitech’s official listing:
- Multi-device: Easy-Switch buttons pair up to three devices over Bluetooth and hop between them instantly — laptop, tablet, phone.
- Cross-OS: auto-maps to Windows, macOS, iPadOS, iOS, Android and ChromeOS, with shared key labels; the fn row is customizable in Logi Options+.
- Battery: up to 36 months on two AAA batteries — no charging, ever.
- Portable: a slim, compact layout (no numpad) at roughly the weight of a paperback, designed to slide into a bag with a tablet.
- Generation note: this is the 2023 “Pebble Keys 2” refresh (K380s) of the original 2015 K380 — same recipe, updated Bluetooth LE and recycled plastics.
What reviewers love
- The typing sound — or lack of it. The scooped round keys are consistently described as some of the quietest anywhere, a fixture of “best keyboard for shared spaces” lists.
- Multi-device switching that just works: tap a button, and you’re typing on your phone; tap again, back to the laptop.
- Ten years of proven demand: the K380 line’s popularity isn’t a launch spike — it has been a steady search-interest staple since 2015, which is precisely the axis this pick is chosen on.
Worth knowing before you buy
- No numpad, no backlight — this is a minimalist travel-and-desk board, not a full workstation deck.
- Round keycaps divide people: most adjust in a day; some never love the shape. It’s the one genuinely subjective thing about the board.
- Bluetooth only: there’s no USB receiver in the box (the Logi Bolt path belongs to its pricier siblings), so very old desktops may need a dongle.
- Buying used/older stock? The original K380 is still everywhere and looks similar — the K380s is the newer model with the longer battery rating.
Who it’s for
Tablet-first workers, hot-deskers, and anyone who wants one quiet, pocketable keyboard shared across every device they own — the same person the K380 has served for ten years.
