Short answer: the Ultimate Ears Boom 3, if you are buying new. The Soundcore Motion 100 ranks higher than it (#45 vs #114 of 175 medium speakers, 3.7/5 vs 2.9/5) but is discontinued, so only consider it used; the Ultimate Ears Boom 3 is still sold new at $134.99.
The Soundcore Motion 100 is the better-sounding, deeper-bass choice. Its bass reaches about 65Hz before falling 10dB, against 91Hz for the Ultimate Ears Boom 3. It supports LDAC Bluetooth, which the Ultimate Ears Boom 3 lacks. It charges over USB-C rather than Micro USB. The catch: Not very deep bass, slight distortion.
Why pick the Ultimate Ears Boom 3: 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. The tradeoff: Not stereo, barely any bass, recessed treble.
Buy the Ultimate Ears Boom 3, since the Soundcore Motion 100 is discontinued and only worth hunting down used.

Soundcore Motion 100: $47 Discontinued eBay
Same family: the Soundcore Motion 300 (larger model, ranked higher, rated 4.5/5), the Soundcore Motion X500 (larger model, rated 4.1/5) and the Soundcore Motion X600 (larger model, rated 4.3/5). See every Soundcore Motion generation.
Pros: Use Oluv’s EQ for the flattest response. Measured bass extension of 65Hz (-10dB).
Cons: Not very deep bass, slight distortion. Real-world battery falls well short of the 12-hour claim at higher volumes (closer to 4 hours at max). Charging takes about 5 hours; no charge-out for other devices. Discontinued and no longer sold new.

Ultimate Ears Boom 3: $134.99 Amazon $134.99 eBay
Newer model: the Ultimate Ears Boom 4, ranked higher, rated 2.9/5, released Jun 2024. See every Ultimate Ears Wonderboom, Boom and Megaboom generation.
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.
