Short answer: the Sony ULT Field 3 if sound quality matters most, the Soundcore Flare 2 if price matters most. The Sony ULT Field 3 ranks #57 of 136 medium speakers at $148. The Soundcore Flare 2 ranks #105 at $80, $68 cheaper.
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.
What the Soundcore Flare 2 offers: Try Alan Ross’s EQ for it Watch for: Rolled off treble. Thuddy bass. Not technically a 360 speaker, only front and rear.
Buy the Sony ULT Field 3 if sound quality matters more than the price. Buy the Soundcore Flare 2 if the price matters more than sound quality.
The Soundcore Flare 2 is not a sound-quality pick. It sits near the bottom of the 136 medium speakers; there are better options higher up.
Battery life favors the Sony ULT Field 3: rated for 24 hours against 12 hours for the Soundcore Flare 2.
