Short answer: the B&O Beosound Explore on measured sound quality, the Ultimate Ears Roll 2 on price, though neither ranks well in its class. The B&O Beosound Explore ranks #114 of 144 medium speakers, rated 2.5/5, at $294.99. The Ultimate Ears Roll 2 ranks #130, rated 2.2/5, at $100, $194.99 cheaper. Both are rated below 3.0/5 among the 144 medium speakers, and the Earfun Uboom L, ranked #1 at $49.79, is a better place to start if sound quality matters.
The case for the B&O Beosound Explore: IP67 rated with a rugged ‘seatbelt’ strap and carabiner hook. The tradeoff: Huge lack of bass extension compared to competitors, overly hot ringing treble.
The case for the Ultimate Ears Roll 2: Thin, flat profile fits easily in a bag or purse; light at 0.73 lb. The catch: Not stereo.
One note: the Ultimate Ears Roll 2 is discontinued and no longer widely available new.
Buy the B&O Beosound Explore when sound quality outweighs the price for you, and the Ultimate Ears Roll 2 when the price outweighs sound quality instead.
There is a real battery-life gap here: the B&O Beosound Explore is rated for 27 hours, the Ultimate Ears Roll 2 only 9 hours.
