Overview

The Logitech PEBBLE KEYS 2 K380sGR is a refreshed take on the long-selling K380 series, updating both the color palette and the feature set. The Graphite finish uses a two-tone design, joining Off-White and Rose as renewed colors, while Greige and Blue are new additions to the lineup. This keyboard keeps the slim, lightweight philosophy of the original, weighing in at roughly 415g.
Battery life is rated at up to 36 months from two AAA batteries, which is a meaningful improvement over the previous generation. The Japanese layout is paired with broad OS support, covering Windows, macOS, iPadOS, Android, and Chrome OS. Beyond Bluetooth, the keyboard now works with Logitech's own Logi Bolt receiver, giving users more flexibility in how they connect.

Connectivity & Compatibility

Two wireless connection paths are available: standard Bluetooth and the Logi Bolt receiver. Bluetooth mode supports Windows 10/11 and later, macOS 11 and later, iPadOS 14 and later, Android OS 9.0 and later, and Chrome OS. The Logi Bolt USB receiver is sold separately, and the older Unifying receiver is not supported, so check your existing accessories before buying.
Easy-Switch lets you pair up to three devices and toggle between them using dedicated keys on the top row. That makes it practical for moving between a laptop, tablet, and phone throughout the day. The wide OS compatibility means it can serve as a single keyboard for a mixed-device household or workspace.

Product Info

This keyboard sits in the entry-to-mid tier of Logitech's wireless keyboard lineup. It builds on the K380 foundation by adding new color options and Logi Bolt support, positioning it as a sensible upgrade for anyone who liked the original but wanted more connection choices. The price point is approachable, making it a low-risk purchase for first-time wireless keyboard users or as a secondary board.
The warranty period is two years, and it is sold as an official domestic product in Japan. The slim, compact body remains the core appeal, with the functional updates layered on top.

Best Use Cases

  • People who switch between a home desktop and an office laptop: the dual Bluetooth/Logi Bolt support and three-device Easy-Switch make it easy to move between machines. Not ideal if you need a number pad for spreadsheet-heavy work.
  • Tablet or phone users who type a lot: iPadOS and Android support plus quick device switching make it a solid companion for on-the-go typing. Gamers should look elsewhere, as this is not built for low-latency play.
  • Minimalists who want a clean desk: the wireless design removes cable clutter, and the slim profile stores easily. If you need dedicated media keys or backlighting, this keyboard does not offer them.
