Why it sits behind the Soundcore 3 A3117

The Soundcore 3 A3117 (9.1) beats the Marshall Emberton III (9.0) because it leaves owners a little happier and has been rated by more owners. The Marshall Emberton III is the newer design, but not by enough to close the gap.

About the Marshall Emberton III

The Emberton III is a 160 x 68 x 76.9 mm speaker that weighs 0.67 kg. The casing copies Marshall's amplifier look, with a textured finish and a metal grille, and the top has a multi-directional jog control, a power button, a pairing button and a battery indicator. A built-in microphone handles hands-free calls. It comes in eight colourways, including Black and Brass, Cream, Brown, Sage, Midnight Blue and Pitch Black.

Inside are a 2-inch, 10 W full-range driver and two passive radiators, driven by a 2 x 38 W Class D amplifier. Marshall calls the output True Stereophonic, a 360-degree spread rather than a left and right split. Frequency range is 65 to 20,000 Hz, with a maximum of 90 dB SPL at 1 m. Bluetooth is 5.3 LE with a range of up to 100 m in free field, and multipoint lets two devices stay connected.

Battery life is 32+ hours, a full charge takes about 2 hours, and 20 minutes on charge gives about 6 hours of playback. Charging is by USB-C. The IP67 rating covers dust and submersion in 1 m of water for up to 30 minutes. The Marshall Bluetooth app (iOS and Android) adjusts the sound. One caution on the pros list: Marshall describes the speaker as LE Audio-ready for Auracast sharing once source devices support it, and does not list Auracast as a current feature. In the box are the speaker, a USB-C cable and the manual. The strap comes only with the Brown colourway.

What owners report about the Marshall Emberton III

No UK retailer owner reviews or owner forum threads could be opened for this model, so this page does not report a pattern of owner feedback.

Who the Marshall Emberton III suits

Buy it if you want a small speaker that sounds fuller and warmer than most of its size, and that lasts several days of casual use between charges. The IP67 rating suits a garden, a beach bag or a bathroom shelf. The amp styling is the main reason to choose it over plainer rivals, and the app offers a few sound presets.

Look elsewhere if you want neutral tuning: the Bose SoundLink Flex (2nd Gen) is described as smoother and more balanced, with a better microphone. For louder garden or party use, the JBL Charge 6 is the bigger choice. If weight matters, the JBL Go 5 or Ultimate Ues WONDERBOOM 4 are lighter, loop-equipped options.

How we score it

Every score here comes from our ranking model; no editor sets the order. Too few review sites cover bluetooth speakers for their verdicts to lead, so this ranking is led by owners. It ranks products by how happy owners are, holding back any product few owners have rated until more agree. How many rated it and how new it is only settle close calls, and value for money earns its own badge rather than a higher place. We compared 20 models for this guide before settling on these ten.

Brands can't pay to be included or to move up. We last checked these picks in November 2026.
