Short answer: the Minirig 4. It ranks #7 of 177 medium speakers by sound quality, rated 4.3/5, at $229.95; the B&O Beosound Explore ranks #142, rated 2.5/5, and costs $294.99, so there is little reason to consider the other one.
The Minirig 4 is the better-sounding, deeper-bass option. A small, long lasting speaker that gets loud and can add a matching subwoofer, with a 30 hour battery. Its bass reaches about 56Hz before falling 10dB, against 70Hz for the B&O Beosound Explore. It supports AAC Bluetooth, which the B&O Beosound Explore lacks. It keeps a wired aux input, which the B&O Beosound Explore lacks. The tradeoff: Calls itself splash resistant and has no official water rating.
The B&O Beosound Explore is the tougher choice. A rugged waterproof speaker with an anodized aluminum design, a strap and carabiner, and a long real world battery. It is rated IP67 against Splash resistant for the Minirig 4. It plays in stereo from a single unit, unlike the Minirig 4. The tradeoff: Huge lack of bass extension compared to competitors, overly hot ringing treble.
Buy the Minirig 4. It is rated higher for sound quality than the B&O Beosound Explore and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
