Natural sounding bass, clearly audible details and balanced, lively sound - this is what the perfect speaker should sound like. However, good sound quality is not everything: Stiftung Warentest also expects a test-winning speaker to be easy to use, have a long-lasting battery and consume little power...

Marshall's small sound box offers good sound and a surprisingly powerful battery for its size. However, it is not cheap.

With the Emberton III, Marshall continues to move in a good direction. The speaker looks great, is waterproof and is easy to control. The sound is convincing, but voices sound distorted. Extras such as a power bank function or additional playback sources are completely missing. However, the long battery life and neat app are impressive.
