Our take on the Marshall KILBURN3BAB Kilburn III Portable Bluetooth Speaker

The Marshall Kilburn III is a portable Bluetooth speaker built around a long-running battery, a rugged dust- and water-resistant body and true stereophonic sound. Its dynamic loudness adjusts tone as you change volume, so it holds up at low and high levels, and tactile top-panel controls keep operation simple. A charging bank lets you top up a phone from the speaker. It suits people who want room-filling sound indoors and out and don't mind a larger, heavier speaker. Against smaller rivals it trades pocketability for louder output and far longer playtime.
