Short answer: the W-King D320. It ranks #51 of 175 medium speakers by sound quality, rated 3.6/5, at $52.92; the Marshall Emberton III ranks #126, rated 2.7/5, and costs $129.99, so there is not much of a tradeoff to weigh.
The W-King D320 is the better-sounding 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 keeps a wired aux input, which the Marshall Emberton III lacks. Watch for: A single D320 is not stereo, and its warm balance trades away some detail and upper-treble air.
The Marshall Emberton III is the longer-running, lighter pick. 30 hour battery life: among the best in its class; a 20 min quick-charge gives 4 hours. It is rated for 32 hours of battery against 24 for the W-King D320. At 1.5 lbs (673 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: Strange unnatural echo-like sound coloration, bass not as deep as competitors.
Buy the W-King D320. It is rated higher for sound quality than the Marshall Emberton III and costs less, so only choose the other one for a particular feature it 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.

Marshall Emberton III: $129.99 Amazon $129.99 eBay
Older models: the Marshall Emberton II (ranked lower, rated 2.7/5) and the Marshall Emberton (ranked lower, estimated 2.6/5). See every Marshall Portable Speakers generation.
Same family: the Marshall Willen II (smaller model, rated 4/5), the Marshall Middleton II (larger model, rated 4.1/5), the Marshall Stockwell III (larger model, rated 3/5) and the Marshall Kilburn III (larger model, rated 3.8/5).
Pros: 30 hour battery life: among the best in its class; a 20 min quick-charge gives 4 hours. IP67 rated, durable rubbery build using 50% recycled plastic. Measured bass extension of 62Hz (-10dB).
Cons: Strange unnatural echo-like sound coloration, bass not as deep as competitors. Not technically a 360 speaker, only front and rear. Not very loud. Not really any different from the Marshall Emberton II except having the treble turned down a little bit.
