Short answer: the JBL Flip 6. It ranks #12 of 136 medium speakers by sound quality at $114.95; the KEF Muo gen2 ranks #73 and costs $249.99, which makes this an easy call rather than a real tradeoff.
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 KEF Muo gen2 offers: KEF seemed to have fixed the rolled off treble and overall balance Watch for: Lacking deeper bass. Very thuddy bass. Appears to be the exact same hardware but with updated tuning. Bass distorts as volume increases, and the claimed 43Hz extension is really only audible at low listening volumes, with a few seconds of lag after volume changes. Loses most of its bass off-axis. Customer reviews are mixed, ranging from praise for detail at low volume to complaints of a boxy, hollow sound.
Buy the JBL Flip 6. It ranks higher for sound quality than the KEF Muo gen2 and costs less, so the other one has nothing left to offer.
If battery life is a priority, the KEF Muo gen2 is rated for 24 hours versus 12 hours for the JBL Flip 6.
