Short answer: the B&O Beosound Explore is built for toughness, while the Marshall Emberton III is the better choice when long battery life is the priority, though neither ranks well in its class. The Explore has IP67 protection, a proper carry strap, and a carabiner. The Emberton III stretches to a stated 30 hours and adds a useful quick-charge claim. Both are rated below 3.0/5 among the 164 medium speakers, so if sound quality matters, consider the Earfun Uboom L instead, ranked #2 at $49.79.
Sound quality is the compromise on both. The Explore lacks low-bass extension and has a hot, ringing treble, while the Emberton III’s echo-like coloration can make playback sound artificial. Pick the practical advantage you will actually use rather than expecting either to be a neutral mini speaker.
Buy the B&O Beosound Explore if a compact, rugged speaker for travel and outdoor use is the goal.
Buy the Marshall Emberton III if the much longer battery life is worth its less natural tuning.

Pros: IP67 rated with a rugged ‘seatbelt’ strap and carabiner hook. Real-world battery life around 20-24 hours. Distinctive anodized-aluminum design. Measured bass extension of ~70Hz (-10dB).
Cons: Huge lack of bass extension compared to competitors, overly hot ringing treble. Colored midrange. Just not great sounding overall.

Marshall Emberton III: $129.99 Amazon eBay
Older model: the Marshall Emberton II (ranked lower, rated 2.7/5).
Smaller model: the Marshall Willen II (rated 4/5).
Larger model: the Marshall Middleton (rated 4/5).
Pros: 30 hour battery life: among the best in its class; a 20 min quick-charge gives 4 hours. IP67 rated, durable rubbery build using 50% recycled plastic. Measured bass extension of 62Hz (-10dB).
Cons: Strange unnatural echo-like sound coloration, bass not as deep as competitors. Not technically a 360 speaker, only front and rear. Not very loud. Not really any different from the Emberton II except having the treble turned down a little bit.
