Short answer: the W-King D320. It ranks #47 of 150 medium speakers by sound quality, rated 3.6/5, at $52.92; the JBL Flip Essential 2 ranks #71, rated 3.3/5, and costs $85.90, which makes this an easy call rather than a real tradeoff.
What the W-King D320 does well: 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. The tradeoff: A single D320 is not stereo, and its warm balance trades away some detail and upper-treble air.
Why pick the JBL Flip Essential 2: Essentially a Flip 5 in a new shell: the same single 44 x 80mm racetrack driver and 20W amplifier, rated down to 65Hz. The catch: There is no tweeter, and side by side comparisons found it does not sound as good as the Flip 6, with less bass; its bass stops growing above about 70% volume, so turning it up mostly adds loudness, not weight.
Buy the W-King D320. It is rated higher for sound quality than the JBL Flip Essential 2 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.

The Two Speakers In Full
W-King D320: $69.99 AliExpress 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.

JBL Flip Essential 2: $85.90 Amazon eBay
Older model: the JBL Flip Essential (ranked lower, rated 3.2/5).
Pros: Essentially a Flip 5 in a new shell: the same single 44 x 80mm racetrack driver and 20W amplifier, rated down to 65Hz. In a side by side loudness test it got louder than the JBL Grip, and listeners comparing it with the Marshall Emberton found it more open sounding and clearer. IPX7 waterproof, 520 g, USB-C charging and Bluetooth 5.1 with two phones connected at once.
Cons: There is no tweeter, and side by side comparisons found it does not sound as good as the Flip 6, with less bass; its bass stops growing above about 70% volume, so turning it up mostly adds loudness, not weight. No app, no EQ, no PartyBoost or stereo pairing, a claimed 10 hours of battery, and IPX7 covers water but not dust.
