Short answer: the Soundcore Motion+. It ranks #3 of 136 medium speakers by sound quality at $79.99; the Ultimate Ears Megaboom 4 ranks #132 and costs $200, 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 Megaboom 4 offers: IP67 rated, floats, and finally uses USB-C charging. 20 hour battery life. ‘PartyUp’ feature syncs multiple UE speakers together. Watch for: A lot of distortion at higher volumes. Rolled off treble. Not very loud. They really screwed this up
Buy the Soundcore Motion+. It ranks higher for sound quality than the Ultimate Ears Megaboom 4 and costs less, so there is no real case for the other one.
Skip the Ultimate Ears Megaboom 4 if sound quality matters to you. It ranks near the bottom of the 136 medium speakers.
There is a real battery-life gap here: the Ultimate Ears Megaboom 4 is rated for 20 hours, the Soundcore Motion+ only 12 hours.
