Short answer: the Soundcore Motion X600. It ranks #19 of 77 large speakers by sound quality at $150; the Ultimate Ears Megablast ranks #61 and costs $240, so there is not much of a tradeoff to weigh.
What the Soundcore Motion X600 offers: Firmware 4.2.9 is a big improvement in sound quality over previous releases. Try this Oluv EQ for the best sound quality Watch for: Stock frequency response is wavy. Use spatial mode for best sound quality. Need a different EQ for each volume step. Dip in the upper bass around 120hz. Rising frequency response, treble a little hot. Would be ranked around #20 without the Oluv EQ. Even with the Oluv EQ the bass isn’t very deep and the sound is still a little unnatural.
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 X600. It ranks higher for sound quality than the Ultimate Ears Megablast and costs less, so there is no real case for the other one.
Skip the Ultimate Ears Megablast if sound quality matters to you. It ranks near the bottom of the 77 large speakers.
