Short answer: the JBL Flip 6. It ranks #12 of 136 medium speakers by sound quality at $114.95; the Marshall Emberton III ranks #99 and costs $165.04, so there is not much of a tradeoff to weigh.
What the JBL Flip 6 offers: A very neutral speaker, very small, almost pocket size, a huge sound quality leap over the Flip 5. Watch for: Not stereo. Some slight upper mids emphasis. The TL version (made in Vietnam) tweeter can sound somewhat scratchy and doesn’t sound as good as the GG version (made in China)
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 JBL Flip 6. It ranks higher for sound quality than the Marshall Emberton III and costs less, which settles it without a real tradeoff to make.
If battery life is a priority, the Marshall Emberton III is rated for 32 hours versus 12 hours for the JBL Flip 6.
