Short answer: the Bose Soundlink Revolve+ II. It ranks #52 of 175 medium speakers by sound quality, rated 3.6/5, at $299. The Sony ULT Field 1 ranks #100, rated 3.1/5, at $138, $161 cheaper, a saving that is not big enough to make up the sound-quality gap.
The Bose Soundlink Revolve+ II is the better-sounding, longer-running option. True 360° sound stays consistent no matter where you stand around it, unlike most portable speakers. It is rated for 17 hours of battery against 12 for the Sony ULT Field 1. It keeps a wired aux input, which the Sony ULT Field 1 lacks. The catch: Overly boosted bass, warm sounding.
The Sony ULT Field 1 is the lighter, tougher choice. IP67 rated, survives drops and 1m submersion. At 1.4 lbs (650 g) it weighs noticeably less than the Bose Soundlink Revolve+ II at 2 lbs (910 g). It is rated IP67 against IP55 for the Bose Soundlink Revolve+ II. It supports AAC Bluetooth, which the Bose Soundlink Revolve+ II lacks. The tradeoff: Upper midrange peak, rolled off treble.
Buy the Bose Soundlink Revolve+ II. It is rated higher for sound quality, and the $161 you would save on the Sony ULT Field 1 does not close the gap.
