Short answer: the B&O Beosound Explore, though neither ranks well in its class. It ranks #132 of 164 medium speakers by sound quality (rated 2.5/5) at $294.99 and is still sold new; the Ultimate Ears Roll 2 ranks #150 (rated 2.2/5) and is discontinued, so it is only an option used. The Ultimate Ears Roll 2’s replacement, the Ultimate Ears Miniroll, is still sold new. Both are rated below 3.0/5 among the 164 medium speakers, and the Earfun Uboom L, ranked #2 at $49.79, is a better place to start if sound quality matters.
The B&O Beosound Explore is the longer-running option. IP67 rated with a rugged ‘seatbelt’ strap and carabiner hook. It is rated for 27 hours of battery against 9 for the Ultimate Ears Roll 2. It plays in stereo from a single unit, unlike the Ultimate Ears Roll 2. It charges over USB-C rather than Micro USB. The catch: Huge lack of bass extension compared to competitors, overly hot ringing treble.
The Ultimate Ears Roll 2 is the lighter choice. Thin, flat profile fits easily in a bag or purse. At 0.7 lbs (330 g) it weighs much less than the B&O Beosound Explore at 1.4 lbs (631 g). It keeps a wired aux input, which the B&O Beosound Explore lacks. The tradeoff: Barely any bass, rolled off treble off axis.
Buy the B&O Beosound Explore. It is rated higher for sound quality and still sold new, while the Ultimate Ears Roll 2 is discontinued.
