Short answer: the W-King D320. It ranks #51 of 175 medium speakers by sound quality (rated 3.6/5) at $52.92 and is still sold new; the Sony XB23 ranks #84 (rated 3.3/5) and is discontinued, so it is only an option used. The Sony XB23’s replacement, the Sony ULT Field 1, is rated 3.1/5 at $138.
The W-King D320 is the better-sounding, longer-running option. A 3.1 lbs (1.4 kg), IP67-rated travel speaker with claimed 40W output, USB-C charging, aux and microSD playback, speakerphone capability and an app with adjustable EQ. It is rated for 24 hours of battery against 12 for the Sony XB23. It is rated IP67 against IPX4 for the Sony XB23. It keeps a wired aux input, which the Sony XB23 lacks. Watch for: A single D320 is not stereo, and its warm balance trades away some detail and upper-treble air.
The Sony XB23 is the lighter option. Reasonably neutral. At 1.3 lbs (580 g) it weighs much less than the W-King D320 at 3.1 lbs (1.4 kg). It plays in stereo from a single unit, unlike the W-King D320. The tradeoff: Bass drops off a ton at high levels.
Buy the W-King D320. It is rated higher for sound quality and still sold new, while the Sony XB23 is discontinued.

W-King D320: $52.92 AliExpress $52.92 eBay
Pros: A 1.4kg, IP67-rated travel speaker with claimed 40W output, USB-C charging, aux and microSD playback, speakerphone capability and an app with adjustable EQ. Owner reports praise its loud, deep-for-size bass and long runtime, while its two tweeters and passive radiators make it a capable choice for casual outdoor listening.
Cons: A single D320 is not stereo, and its warm balance trades away some detail and upper-treble air. The claimed 100Hz low-frequency specification suggests that its perceived bass should not be mistaken for true sub-bass; evaluate its tuning with the app rather than expecting a neutral default.
