Short answer: the Soundcore Motion X600. It ranks #19 of 77 large speakers by sound quality at $150; the Ultimate Ears Epicboom ranks #57 and costs $213.41, which makes this an easy call rather than a real tradeoff.
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 Epicboom offers: 17 hour battery with USB-C charging (first UE portable with USB-C). IP67 rating, floats in water. Made mostly from recycled fabric and plastic. Large best-sounding UE portable that still feels portable. 180ft Bluetooth range. Watch for: Not very deep bass for the size. Gets distorted at around 70-80% with bass thuds.
Buy the Soundcore Motion X600. It ranks higher for sound quality than the Ultimate Ears Epicboom and costs less, which settles it without a real tradeoff to make.
