Short answer: the Sony ULT Field 3 on measured sound quality, the Soundcore 2 on price. The Sony ULT Field 3 ranks #57 of 136 medium speakers at $148. The Soundcore 2 ranks #81 at $29.98, $118.02 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 2 offers: 24+ hour battery life from a 5200mAh cell. Very light (0.8 lb) and compact. IPX7 rated with a soft, grippy silicone coating. Watch for: Bass doesn’t go as deep as others
Buy the Sony ULT Field 3 if sound quality is the priority over the price, or the Soundcore 2 if the price is the priority over sound quality.
