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 SRS-XB20 ranks #120 (rated 2.8/5) and is discontinued, so it is only an option used. The Sony SRS-XB20’s replacement, the Sony ULT Field 1, is rated 3.1/5 at $138.
The W-King D320 is the better-sounding, longer-running pick. 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 SRS-XB20. It is rated IP67 against IPX5 for the Sony SRS-XB20. It has an adjustable EQ, which the Sony SRS-XB20 lacks. The tradeoff: A single D320 is not stereo, and its warm balance trades away some detail and upper-treble air.
The Sony SRS-XB20 is the lighter pick. At 1.3 lbs (590 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. Watch for: Sounds thin at higher volumes.
Buy the W-King D320. It is rated higher for sound quality; the Sony SRS-XB20 is no longer sold new.

The Two Speakers In Full
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.
