Short answer: the Wonderboom 3 for durability, the Flare 2 for tuning, though neither ranks well in its class. The Wonderboom 3 is IP67 rated, floats and is rated to survive a 5 ft drop onto hard surfaces at $85.99, but it is not stereo and the notes flag barely any bass. The Flare 2 costs $80 and its rolled off treble is fixable with Alan Ross’s EQ. Both are rated below 3.0/5 among the 164 medium speakers, and the Earfun Uboom L, ranked #2 at $49.79, is a better place to start if sound quality matters.
Buy the Ultimate Ears Wonderboom 3. It is rated higher for sound quality; the Soundcore Flare 2 is no longer sold new.

Ultimate Ears Wonderboom 3: $85.99 Amazon eBay
Newer model: the Ultimate Ears Wonderboom 4, ranked higher, rated 2.9/5.
Pros: IP67 rated, floats, and is rated to survive a 5 ft drop onto hard surfaces. 14 hour battery: longer than the Wonderboom 2. Measured bass extension of 76Hz (-10dB).
Cons: Not stereo, barely any bass. Boosted 93Hz upper bass. Cuts bass heavily at high volume. 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 2022. Not technically a 360 speaker, only front and rear.
