Short answer: the Xiaomi Sound Party. It ranks #19 of 142 medium speakers by sound quality at $133.62; the KEF Muo gen2 ranks #76 and costs $249.99, so there is not much of a tradeoff to weigh.
What the Xiaomi Sound Party offers: An unusually versatile 1.2kg outdoor speaker: IP67 dust/water protection, USB-C power-bank output, NFC pairing, lights, stereo pairing and a claimed 26-hour battery life. Several independent reviews describe a warm, generally balanced sound with clear vocals and useful bass impact when Bass Boost is off. It is also easy to carry thanks to the retractable handle. Watch for: The sound evidence is mixed rather than universally glowing. One lab review found it loud but flat and unclean with blurred treble, while others hear the Bass Boost mode as boomy upper bass that can bottom out at high volume. It is not the strongest choice for a large party: tested output is around 94dB and rivals such as the Soundcore Boom 2 play louder with deeper bass. SBC is the only Bluetooth codec and there is no aux input.
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 Party. It ranks higher for sound quality than the KEF Muo gen2 and costs less, which settles it without a real tradeoff to make.
