Short answer: the Soundcore Motion X500 for stereo sound, the Ultimate Ears Boom 3 for a tougher floating design and PartyUp. The X500 delivers 40W of stereo from a three-driver layout with an IPX7 rating and battery life close to its 12-hour claim, though it is a little bright on top with a peak at 250Hz and a dip at 1kHz. The Boom 3 has a strong 15-hour battery and an IP67 floating shell.
Buy the Ultimate Ears Boom 3 ($134.99) for a medium speaker; the Soundcore Motion X500 ($99.99) suits a large speaker instead.

The Two Speakers In Full
Ultimate Ears Boom 3: $134.99 Amazon eBay
Newer model: the Ultimate Ears Boom 4, ranked higher, rated 2.9/5.
Pros: Rich and warm bass without muddying mix, crisp highs, excellent 15-hour battery life, stable Bluetooth connectivity, IP67 rated and floats, rugged fabric shell, can pair up to 150 speakers via PartyUp. Measured bass extension of 91Hz (-10dB).
Cons: Not stereo, barely any bass, recessed treble. 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 2021. Lots of mentions of failing batteries on amazon. Not technically a 360 speaker, only front and rear.
