Short answer: the Soundcore Motion Boom. It ranks #14 of 77 large speakers by sound quality at $109.99; the Ultimate Ears Megablast ranks #61 and costs $240, so there is not much of a tradeoff to weigh.
What the Soundcore Motion Boom offers: 30W loud bass-heavy sound, excellent budget-friendly value. 10,000mAh battery for 24 hours claimed (15-18 hours with BassUp engaged at high volume). Waterproof, buoyant design, convenient carry handle. PowerIQ USB port charges devices. BassUp feature works well with clear mids/highs. Watch for: Not as neutral or detailed as other top ranked speakers
What the Ultimate Ears Megablast offers: Alexa integration (Wi-Fi + Bluetooth). 93dB loudest in UE lineup, 40% louder than Megaboom. IP67 waterproof and drop-proof. 16 hour battery. Party mode connects up to 8 speakers. Can use while charging to keep Alexa on 24/7. Watch for: Bass is not very deep compared to the competition
Buy the Soundcore Motion Boom. It ranks higher for sound quality than the Ultimate Ears Megablast and costs less, which settles it without a real tradeoff to make.
If sound quality matters at all to you, skip the Ultimate Ears Megablast. It ranks near the bottom of the 77 large speakers, so look higher up the list instead.
There is a real battery-life gap here: the Soundcore Motion Boom is rated for 24 hours, the Ultimate Ears Megablast only 16 hours.
