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.
- Longest running time tested
- Simple operation via joystick
- Voices somewhat croaky and strained
- No connections
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.
In the speaker test, the best Bluetooth and WiFi devices score highly with their rich sound and ease of use. However, only a few offer this complete package. Natural sounding bass, clearly audible details and balanced, lively sound - this is what the perfect speaker should sound like...

- Compact, stylish, high quality
- Powerful, warm sound
- Enormous battery life & Quick Charge
- Low bass not as powerful as larger speakers
- Control knob somewhat spongy
- AUX input missing
- High-quality, chic retro design
- Water and dust protection according to IP67
- Easy operation through joystick
- Very long battery life
- Sound not convincing with all songs
- Distortion at high volume
