Short answer: the EarFun Uboom L. It ranks #2 of 177 medium speakers by sound quality, rated 4.6/5, at $49.79; 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 EarFun Uboom L is the better-sounding, deeper-bass choice. A great value medium speaker with clear, natural sound, waterproofing, and a Video Mode that keeps audio in sync with video. 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: It cannot produce real low-bass rumble or fill a large, noisy space, and the top end loses some detail.
The B&O Beosound Explore is the longer-running option. A rugged waterproof speaker with an anodized aluminum design, a strap and carabiner, and a long real world battery. It is rated for 27 hours of battery against 16 for the EarFun Uboom L. The catch: Huge lack of bass extension compared to competitors, overly hot ringing treble.
Buy the EarFun Uboom L. It is rated higher for sound quality than the B&O Beosound Explore and costs less, which makes it the one to get unless you need something the other one does better.
