Short answer: the Ultimate Ears Miniroll for sound, the Bose Soundlink Micro for toughness. The Soundlink Micro has a rugged rubberized coating and IP67 rating for 1m submersion for 30 minutes, but its listed flaw is a lack of clarity. The Miniroll is cheaper at $49.99 against $82 and offers good clarity and detail in the mids and highs, with bass that is not quite as deep as the best rated speakers.
Buy the Ultimate Ears Miniroll. It is rated higher for sound quality than the Bose Soundlink Micro and costs less, which makes it the one to get unless you need something the other one does better.
There is a real battery-life gap here: the Ultimate Ears Miniroll is rated for 12 hours, the Bose Soundlink Micro only 6 hours.
