Short answer: the JBL Charge Essential 3 SE on measured sound quality, the W-King D320 on price. The JBL Charge Essential 3 SE ranks #40 of 150 medium speakers, rated 3.7/5, at $199.95. The W-King D320 ranks #47, rated 3.6/5, at $52.92, $147.03 cheaper.
Why pick the JBL Charge Essential 3 SE: Gets louder than the Bose SoundLink Flex 2nd Gen and digs deeper in the bass, with a separate 20mm tweeter, two passive radiators and 40W of amplification in the familiar Charge body. The catch: In side-by-side listening against the Charge 6, its bass is weaker and less stable and distorts on bass-heavy tracks even with the bass turned down in the app, while a narrow boost in the upper mids makes it sound less natural.
Why pick the W-King D320: 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.
Buy the JBL Charge Essential 3 SE if sound quality is the priority over the price, or the W-King D320 if the price is the priority over sound quality.

The Two Speakers In Full
JBL Charge Essential 3 SE: $199.95 JBL eBay
Older models: the JBL Charge Essential 2 (ranked higher, rated 3.8/5) and the JBL Charge Essential (ranked lower, rated 3.2/5).
Pros: Gets louder than the Bose SoundLink Flex 2nd Gen and digs deeper in the bass, with a separate 20mm tweeter, two passive radiators and 40W of amplification in the familiar Charge body. IP67 water and dust protection, a claimed 20 hours of battery life, a USB-C power bank output, Auracast stereo pairing and multi-speaker linking, Bluetooth 5.4 with AAC, and app EQ.
Cons: In side-by-side listening against the Charge 6, its bass is weaker and less stable and distorts on bass-heavy tracks even with the bass turned down in the app, while a narrow boost in the upper mids makes it sound less natural. Against the Bose SoundLink Flex 2nd Gen it sounds muddier and more strident, with less detail and a smaller soundstage. At full price it costs as much as the Charge 6, which is the better speaker.

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.
