Short answer: the JBL Flip 7 for a neutral small speaker, the Ultimate Ears Boom 3 for battery and floating. The Boom 3 is IP67 rated and floats, with an excellent 15-hour battery life and a rugged fabric shell, and PartyUp can pair up to 150 speakers, but it is not stereo with recessed treble, and the notes call its micro USB port inexcusable for a 2021 product. The Flip 7 is very neutral and almost pocket size, with a 4kHz bump against it.
Buy the JBL Flip 7. It is rated higher for sound quality than the Ultimate Ears Boom 3 and costs less, which makes it the one to get unless you need something the other one does better.

The Two Speakers In Full
JBL Flip 7: $119.95 Amazon eBay
Older models: the JBL Flip 6 (ranked higher, rated 4.2/5), the JBL Flip 5 (ranked lower, rated 3.3/5) and the JBL Flip 4 (ranked lower, rated 3.3/5).
Pros: A very neutral speaker, very small, almost pocket size. Just slightly more treble than the Flip 6 which was already a great speaker. Slightly deeper bass than the Flip 6. IP68 protection, a 7-band app EQ, Auracast and a USB-C digital audio input. Measured bass extension of 59Hz (-10dB).
Cons: A little bit of a bump at 4kHz, not quite as neutral as the Flip 6. On balance it is the slightly worse of the two.

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.
