Short answer: the W-King D320. It ranks #44 of 136 medium speakers by sound quality at $69.99; the JBL Flip Essential ranks #66 and costs $130, which makes this an easy call rather than a real tradeoff.
What the W-King D320 offers: 40W output power, IP67 waterproof, 24-hour battery life, customizable EQ app with 6 preset modes, Bluetooth 5.3, AUX and MicroSD support, dual tweeters with passive radiators, USB-C charging Watch for: Not stereo. Warm tuning. Lacking some detail. Rolled off treble
What the JBL Flip Essential offers: Aux input for wired sources. IPX7 rated. Genuinely portable at under a pound; a cheaper, more basic alternative to the Flip 5. Watch for: Less bass than a Flip 5.
Buy the W-King D320. It ranks higher for sound quality than the JBL Flip Essential and costs less, so the other one has nothing left to offer.
There is a real battery-life gap here: the W-King D320 is rated for 24 hours, the JBL Flip Essential only 10 hours.
