Short answer: the Bose Soundlink Mini 2 if sound quality matters most, the Ultimate Ears Wonderboom 2 if price matters most. The Bose Soundlink Mini 2 ranks #55 of 136 medium speakers at $184. The Ultimate Ears Wonderboom 2 ranks #86 at $80, $104 cheaper.
What the Bose Soundlink Mini 2 offers: Compact aluminum build feels sturdy and dense. ~10 hour battery life; can pair to two devices at once and remembers up to 8. Watch for: Boosted upper bass like most Bose speakers. Upper treble rolled off. Bass is 2db less boosted than the Mini. Bass doesn’t go as deep as others. Failures of the mainboard are common.
What the Ultimate Ears Wonderboom 2 offers: IP67 rated and floats. Compact and light enough to toss in a bag. Watch for: Not stereo, barely any bass, recessed treble. Slightly boosted 93hz upper bass Dip at 9khz. You can tell from the micro USB that they are just feeding you the same crap hardware over and over, this is inexcusable for a product released in 2019. Not technically a 360 speaker, only front and rear.
Buy the Bose Soundlink Mini 2 if sound quality is the priority over the price, or the Ultimate Ears Wonderboom 2 if the price is the priority over sound quality.
If water resistance matters to you, the Ultimate Ears Wonderboom 2 at IP67 (brief submersion) holds up far better than the Bose Soundlink Mini 2 at no water resistance.
