Short answer: the Ultimate Ears Wonderboom. It ranks #87 of 136 medium speakers by sound quality at $79; the Soundcore Flare 2 ranks #105 and costs $80, so there is not much of a tradeoff to weigh.
What the Soundcore Flare 2 gets right: Try Alan Ross’s EQ for it. The tradeoff: Rolled off treble.
What the Ultimate Ears Wonderboom offers: IP67 rated and floats. Set against that: Not stereo, barely any bass, recessed treble.
One note: the Ultimate Ears Wonderboom is discontinued, but it still ranks #87 of 136 medium speakers by sound quality, ahead of most of what is still sold new, so it is worth considering used.
Buy the Ultimate Ears Wonderboom. It ranks higher for sound quality than the Soundcore Flare 2 and costs less, so there is no real case for the other one.
If sound quality matters at all to you, skip the Soundcore Flare 2. It ranks near the bottom of the 136 medium speakers, so look higher up the list instead.
