Short answer: the W-King D320. It ranks #51 of 175 medium speakers by sound quality, rated 3.6/5, at $52.92; the KEF Muo gen2 ranks #97, rated 3.1/5, and costs $249.99, so there is little reason to consider the other one.
The W-King D320 is the better-sounding 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 keeps a wired aux input, which the KEF Muo gen2 lacks. Watch for: A single D320 is not stereo, and its warm balance trades away some detail and upper-treble air.
The KEF Muo gen2 is the lighter choice. KEF seemed to have fixed the rolled off treble and overall balance. At 1.6 lbs (740 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 catch: Lacking deeper bass.
Buy the W-King D320. It is rated higher for sound quality than the KEF Muo gen2 and costs less, which makes it the one to get unless you need something the other one does better.

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.

KEF Muo gen2: $249.99 Amazon $249.99 eBay
Pros: KEF seemed to have fixed the rolled off treble and overall balance
Cons: Lacking deeper bass. Very thuddy bass. Appears to be the exact same hardware but with updated tuning. Bass distorts as volume increases, and the claimed 43Hz extension is really only audible at low listening volumes, with a few seconds of lag after volume changes. Loses most of its bass off-axis. Customer reviews are mixed, ranging from praise for detail at low volume to complaints of a boxy, hollow sound.
