Short answer: the Xiaomi Sound Party for better sound quality, the Ultimate Ears Wonderboom 4 for the lower price. The Xiaomi Sound Party ranks #19 of 142 medium speakers at $133.62. The Ultimate Ears Wonderboom 4 ranks #87 at $59.99, $73.63 cheaper.
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 Ultimate Ears Wonderboom 4 offers: Small size. Watch for: Bass isn’t as deep as the top-ranked speakers and is a little thuddy. Not much improvement over the previous Ultimate Ears Wonderboom 3 besides the USB-C charging port.
Buy the Xiaomi Sound Party when sound quality outweighs the price for you, and the Ultimate Ears Wonderboom 4 when the price outweighs sound quality instead.
There is a real battery-life gap here: the Xiaomi Sound Party is rated for 26 hours, the Ultimate Ears Wonderboom 4 only 14 hours.
