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. 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.
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.
On the B&O Beosound Explore side: IP67 rated with a rugged ‘seatbelt’ strap and carabiner hook. Watch for: Huge lack of bass extension compared to competitors, overly hot ringing treble.
What the Marshall Emberton III gets right: 30 hour battery life, among the best in its class; a 20 min quick-charge gives 4 hours. The tradeoff: Strange unnatural echo-like sound coloration, bass not as deep as competitors.
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.
The B&O Beosound Explore is not a sound-quality pick. It sits near the bottom of the 142 medium speakers; there are better options higher up.

Marshall Emberton III: $159.99 Amazon eBay
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.
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.
