Last updated: August 28, 2026

Short answer: the W-King D320. It ranks #44 of 136 medium speakers by sound quality at $69.99; the Marshall Emberton III ranks #99 and costs $165.04, so there is not much of a tradeoff to weigh.

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 Marshall Emberton III offers: 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. Watch for: 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 Emberton II except having the treble turned down a little bit.

Buy the W-King D320. It ranks higher for sound quality than the Marshall Emberton III and costs less, which settles it without a real tradeoff to make.
