Short answer: the Xiaomi Sound Party. It ranks #20 of 177 medium speakers by sound quality, rated 4.1/5, at $149.99; the KEF Muo gen2 ranks #96, rated 3.1/5, and costs $249.99, so there is not much of a tradeoff to weigh.
The Xiaomi Sound Party is the better-sounding pick. A versatile outdoor speaker with warm, balanced sound, fully waterproof build, long battery life, a phone charging port and a handy retractable handle. The tradeoff: The sound evidence is mixed rather than universally glowing.
The KEF Muo gen2 is the lighter pick. A stylish waterproof stereo speaker with aptX Adaptive, USB-C audio input, Auracast and long battery life. At 1.6 lbs (740 g) it weighs much less than the Xiaomi Sound Party at 2.6 lbs (1.2 kg). It supports aptX Adaptive Bluetooth, which the Xiaomi Sound Party lacks. It plays in stereo from a single unit, unlike the Xiaomi Sound Party. Watch for: Lacking deeper bass.
Buy the Xiaomi Sound Party. It is rated higher for sound quality than the KEF Muo gen2 and costs less, so only choose the other one for a particular feature it does better.
