Short answer: the Soundcore Motion+. It ranks #3 of 136 medium speakers by sound quality at $79.99; the Ultimate Ears Boom 3 ranks #89 and costs $129.90, so there is not much of a tradeoff to weigh.
What the Soundcore Motion+ offers: The previous best sounding in class, still a great speaker with separate tweeters, more bass at full volume and better off-axis treble frequency response than the Uboom L. Just okay with the default EQ, I highly recommend using this EQ setting from r/kai7895 to get it more neutral. To achieve the absolute best sound you’ll need the Wavelet app (Android only) and set the provided Wavelet EQ in there too. Turn off the wavelet EQ for outdoor use. An alternative is Oluv’s EQ which only needs the Soundcore app EQ. Watch for: Not quite as neutral or detailed as the Uboom L. Without the above EQ, this speaker will rank around #25 in the rankings.
What the Ultimate Ears Boom 3 offers: 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 Watch for: 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.
Buy the Soundcore Motion+. It ranks higher for sound quality than the Ultimate Ears Boom 3 and costs less, so the other one has nothing left to offer.
