Short answer: the Sony ULT Field 3 if sound quality matters most, the JBL Charge 3 if price matters most. The Sony ULT Field 3 ranks #57 of 136 medium speakers at $148. The JBL Charge 3 ranks #67 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 JBL Charge 3 offers: Doubles as a 6000mAh power bank for USB devices. ~20 hour battery life. IPX7 rated; built-in noise/echo-cancelling speakerphone. Watch for: Less clarity than the Flip 4. Battery failures are common.
Buy the Sony ULT Field 3 if sound quality is the priority over the price, or the JBL Charge 3 if the price is the priority over sound quality.
