Short answer: the JBL Xtreme 2. It ranks #44 of 77 large speakers by sound quality at $149.99; the Ultimate Ears Megablast ranks #61 and costs $240, so there is little reason to consider the other one.
What the JBL Xtreme 2 offers: Four drivers with refined bass balance, closer to studio monitors than typical portables. IPX7 water-resistant. Amazing real-world battery: ~20 hours at 75dB (vs 15hr claim). USB-A port charges other devices. Optional carry strap. Watch for: External AC power brick for charging. Boosted bass. Treble harsh at high volumes.
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 JBL Xtreme 2. It ranks higher for sound quality than the Ultimate Ears Megablast and costs less, so there is no real case for the other one.
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.
