Short answer: the Ultimate Ears Wonderboom 3, though neither ranks well in its class. It ranks #96 of 150 medium speakers by sound quality, rated 2.9/5, at $85.99; the Sony SRS-XE300 ranks #103, rated 2.8/5, and costs $97.71, which makes this an easy call rather than a real tradeoff. Both are rated below 3.0/5 among the 150 medium speakers, and the Earfun Uboom L, ranked #1 at $49.79, is a better place to start if sound quality matters.
What the Ultimate Ears Wonderboom 3 does well: IP67 rated, floats, and is rated to survive a 5 ft drop onto hard surfaces. The catch: Not stereo, barely any bass.
What the Sony SRS-XE300 does well: IP67 rated. Watch for: Muffled sounding, not very deep bass.
One note: the Sony SRS-XE300 is no longer in production and isn’t widely stocked new anymore.
Buy the Ultimate Ears Wonderboom 3. It is rated higher for sound quality than the Sony SRS-XE300 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
If battery life is a priority, the Sony SRS-XE300 is rated for 24 hours versus 14 hours for the Ultimate Ears Wonderboom 3.

The Two Speakers In Full
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.
