Short answer: the Bose Soundlink Revolve+ II for better sound quality, the Sony ULT Field 3 for the lower price. The Bose Soundlink Revolve+ II ranks #45 of 136 medium speakers at $259. The Sony ULT Field 3 ranks #57 at $148, $111 cheaper.
What the Bose Soundlink Revolve+ II offers: True 360° sound stays consistent no matter where you stand around it, unlike most portable speakers. Watch for: Overly boosted bass, warm sounding. Boosted mids. Rolled off treble. Only IP55.
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 Bose Soundlink Revolve+ II if sound quality matters more than the price. Buy the Sony ULT Field 3 if the price matters more than sound quality.
