Short answer: the Soundcore Glow. It ranks #43 of 136 medium speakers by sound quality at $80; the Sony ULT Field 3 ranks #57 and costs $148, so there is little reason to consider the other one.
What the Soundcore Glow offers: Nice light show. Treble boosted 7db. Not technically a 360 speaker, only front and rear. Watch for: Bass falls off quickly at louder volumes, leaving mostly treble; distortion on bass-heavy tracks at full volume. Light effects and bass-boost noticeably shorten battery life. USB-C port doesn’t support power-bank charging.
What the Sony ULT Field 3 offers: IP67 rated, dustproof and water resistant. 24 hour battery life. App with 10-band EQ. Party Connect with up to 100 speakers. USB-C in/out for charging your phone. Watch for: Sounds a bit hollow, a bit boosted in the treble. Custom EQ and the ULT bass-boost button can’t be used together - turning on ULT disables the EQ. Bass is very weak with ULT off. Lost to the JBL Charge 6 in a side-by-side comparison despite being the larger speaker.
Buy the Soundcore Glow. It ranks higher for sound quality than the Sony ULT Field 3 and costs less, so the other one has nothing left to offer.
