Short answer: the Bose Soundlink Revolve+ II. It ranks #52 of 175 medium speakers by sound quality (rated 3.6/5) at $299 and is still sold new; the Sony XB33 ranks #77 (rated 3.4/5) and is discontinued, so it is only an option used. The Sony XB33’s replacement, the Sony ULT Field 3, is rated 3.4/5 at $208.
The case for the Bose Soundlink Revolve+ II: True 360° sound stays consistent no matter where you stand around it, unlike most portable speakers. It keeps a wired aux input, which the Sony XB33 lacks. The tradeoff: Overly boosted bass, warm sounding.
The Sony XB33 is the longer-running, tougher pick. IP67 rated and lightweight (2.4 lb). It is rated for 24 hours of battery against 17 for the Bose Soundlink Revolve+ II. It is rated IP67 against IP55 for the Bose Soundlink Revolve+ II. It supports LDAC Bluetooth, which the Bose Soundlink Revolve+ II lacks. The tradeoff: Not very loud.
Buy the Bose Soundlink Revolve+ II. It is rated higher for sound quality and still sold new, while the Sony XB33 is discontinued.
