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 JBL Flip Essential ranks #90 (rated 3.2/5) and is discontinued, so it is only an option used. The JBL Flip Essential’s replacement, the JBL Flip Essential 3 SE, is rated 3.6/5 at $113.82.
The W-King D320 is the better-sounding, longer-running choice. 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 10 for the JBL Flip Essential. It has an adjustable EQ, which the JBL Flip Essential lacks. It charges over USB-C rather than Micro USB. The tradeoff: A single D320 is not stereo, and its warm balance trades away some detail and upper-treble air.
The JBL Flip Essential is the lighter option. A genuinely portable 1 lbs (471 g) speaker with IPX7 water resistance, a 3.5mm aux input and 16W output from two full-range drivers. At 1 lbs (471 g) it weighs much less than the W-King D320 at 3.1 lbs (1.4 kg). Watch for: Bass is lighter than the JBL Flip 5 and the 80Hz claimed low-frequency limit means it cannot deliver real low-end weight.
Buy the W-King D320. It is rated higher for sound quality; the JBL Flip Essential 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.

JBL Flip Essential: $130 Discontinued eBay
Newer model: the JBL Flip Essential 3 SE, ranked higher, estimated 3.6/5, released Apr 2026. See every JBL Flip Essential generation.
Pros: A genuinely portable 471g speaker with IPX7 water resistance, a 3.5mm aux input and 16W output from two full-range drivers. It is a simple, no-app option for wired sources, travel and casual listening where its cylindrical shape and modest size are a genuine advantage.
Cons: Bass is lighter than the JBL Flip 5 and the 80Hz claimed low-frequency limit means it cannot deliver real low-end weight. Battery life is only a claimed 10 hours, there is no speakerphone, EQ or party mode, and its older Bluetooth 4.1 platform and discontinued status make it a basic used-market choice.
