Short answer: the Xiaomi Sound Outdoor. It ranks #43 of 142 medium speakers by sound quality at $54.99; the KEF Muo gen2 ranks #76 and costs $249.99, so there is not much of a tradeoff to weigh.
What the Xiaomi Sound Outdoor offers: Xiaomi Sound Outdoor uses 20W woofer, 10W tweeter + 2x passive radiators. Its 597 g, claimed 12 hours (Manufacturer specified) battery life, IP67 protection and mono playback make it a practical option for its intended room or portable use. Watch for: Its 60Hz - 20kHz (Manufacturer specified) specification points to limited deep-bass reach for the cabinet size. There is no companion app. No EQ adjustment.
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 Xiaomi Sound Outdoor. 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 Xiaomi Sound Outdoor only 12 hours.
