Short answer: the Bose Soundlink Mini on measured sound quality, the Ultimate Ears Wonderboom 4 on price. The Bose Soundlink Mini ranks #56 of 136 medium speakers at $125. The Ultimate Ears Wonderboom 4 ranks #84 at $59.99, $65.01 cheaper.
What the Bose Soundlink Mini offers: Compact aluminum build feels sturdy and dense. Comes with a charging cradle. Watch for: Boosted upper bass like most Bose speakers. Upper treble rolled off. Bass doesn’t go as deep as others. Failures of the mainboard are common.
What the Ultimate Ears Wonderboom 4 offers: Small size. Watch for: Bass isn’t as deep as the top-ranked speakers and is a little thuddy. Not much improvement over the previous Ultimate Ears Wonderboom 3 besides the USB-C charging port.
Buy the Bose Soundlink Mini when sound quality outweighs the price for you, and the Ultimate Ears Wonderboom 4 when the price outweighs sound quality instead.
There is a real gap in water resistance: the Ultimate Ears Wonderboom 4 at IP67 (brief submersion) against the Bose Soundlink Mini, which has no water resistance.
