Short answer: the Soundcore Motion 100. It ranks #39 of 136 medium speakers by sound quality at $47; the Ultimate Ears Megaboom 3 ranks #83 and costs $163, so there is not much of a tradeoff to weigh.
What the Soundcore Motion 100 offers: Use Oluv’s EQ for the flattest response Watch for: 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.
What the Ultimate Ears Megaboom 3 offers: IP67 rated, floats, and survives drops from up to 1 meter. 20 hour battery life - about double most speakers this size. Watch for: Not stereo, barely any bass. 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 2018. Not technically a 360 speaker, only front and rear.
Buy the Soundcore Motion 100. It ranks higher for sound quality than the Ultimate Ears Megaboom 3 and costs less, so the other one has nothing left to offer.
There is a real battery-life gap here: the Ultimate Ears Megaboom 3 is rated for 20 hours, the Soundcore Motion 100 only 12 hours.
