Short answer: the Bose Soundlink Mini. It ranks #56 of 136 medium speakers by sound quality at $125; the KEF Muo gen2 ranks #73 and costs $249.99, so there is little reason to consider the other one.
What the Bose Soundlink Mini offers: Compact aluminum build feels sturdy and dense. Comes with a charging cradle. Watch for: Boosted upper bass like most Bose speakers. Upper treble rolled off. Bass doesn’t go as deep as others. Failures of the mainboard are common.
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 Bose Soundlink Mini. 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 Bose Soundlink Mini only 10 hours.
Water resistance is not close: the KEF Muo gen2 is rated at IP67 (brief submersion), well ahead of the Bose Soundlink Mini at no water resistance.
