Short answer: both are discontinued, so this only matters if you are buying used. Used, the Bose Soundlink Mini 2 is the better pick: it ranks #72 of 175 medium speakers by sound quality (rated 3.4/5), against #112 (rated 2.9/5) for the Ultimate Ears Wonderboom. If you want one new, the Ultimate Ears Wonderboom 4 replaces the Ultimate Ears Wonderboom and is rated 2.9/5 at $74.50.
The Bose Soundlink Mini 2 is the better-sounding pick. Compact aluminum build feels sturdy and dense. ~10 hour battery life; can pair to two devices at once and remembers up to 8. It keeps a wired aux input, which the Ultimate Ears Wonderboom lacks. It plays in stereo from a single unit, unlike the Ultimate Ears Wonderboom. Watch for: Boosted upper bass like most Bose speakers.
The Ultimate Ears Wonderboom is the lighter, tougher choice. IP67 rated and floats. At 0.9 lbs (425 g) it weighs much less than the Bose Soundlink Mini 2 at 1.5 lbs (680 g). It is rated IPX7, while the Bose Soundlink Mini 2 has no water resistance. The catch: Not stereo, barely any bass, recessed treble.
Buy the Bose Soundlink Mini 2 only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, buy the Ultimate Ears Wonderboom 4, which replaces the Ultimate Ears Wonderboom.
