Short answer: the Zealot S97. It ranks #46 of 77 large speakers by sound quality at $65.86; the Ultimate Ears Megablast ranks #61 and costs $240, so there is little reason to consider the other one.
What the Zealot S97 offers: There is nothing else for $48 with that deep of bass and a reasonable tuning Watch for: Doesn’t get very loud compared to other speakers in this class. Short battery life. Pretty heavy. Many say the S67 has deeper bass, but also gets more distorted
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 Zealot S97. It ranks higher for sound quality than the Ultimate Ears Megablast and costs less, which settles it without a real tradeoff to make.
The Ultimate Ears Megablast is not a sound-quality pick. It sits near the bottom of the 77 large speakers; there are better options higher up.
