Short answer: the Ultimate Ears Wonderboom 3 on rank and price, though neither ranks well in its class. It sits at #107 of 164 medium speakers at $85.99 against the Emberton II’s #123 of 164 at $144.99, and it is IP67 rated, floats and is rated to survive a 5 ft drop. It is not stereo with barely any bass; the Emberton II runs 30 hours with a 20 minute quick charge for 4 hours but has an echo-like coloration and is not very loud. Both are rated below 3.0/5 among the 164 medium speakers, so if sound quality matters, consider the Earfun Uboom L instead, ranked #2 at $49.79.
Buy the Ultimate Ears Wonderboom 3. It is rated higher for sound quality than the Marshall Emberton II and costs less, so it is the default pick unless a specific strength of the other one matters more to you.

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.
