Short answer: the Ultimate Ears Wonderboom 3 on price and ruggedness, though neither ranks well in its class. It is IP67 rated, floats, survives a 5 ft drop onto hard surfaces and costs $43.01 less, though it is not stereo and has barely any bass. The Sony SRS-XB20 is IPX5 rated with a pill shape that slides easily into a bag, but it sounds thin at higher volumes. Both are rated below 3.0/5 among the 164 medium speakers; for better sound, the Earfun Uboom L ranks #2 at $49.79.
Buy the Ultimate Ears Wonderboom 3. It is rated higher for sound quality, and the Sony SRS-XB20 is discontinued, so it is only available used.

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.
