Short answer: the Soundcore Boost “original model” pre-2021. It ranks #13 of 136 medium speakers by sound quality at $60; the KEF Muo gen2 ranks #73 and costs $249.99, which makes this an easy call rather than a real tradeoff.
What the Soundcore Boost “original model” pre-2021 offers: A great sounding neutral speaker. Watch for: This old version has micro-usb charging. Only IPX5.
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 Soundcore Boost “original model” pre-2021. It ranks higher for sound quality than the KEF Muo gen2 and costs less, which settles it without a real tradeoff to make.
There is a real battery-life gap here: the KEF Muo gen2 is rated for 24 hours, the Soundcore Boost “original model” pre-2021 only 12 hours.
