Short answer: the EarFun Uboom L. It ranks #2 of 177 medium speakers by sound quality, rated 4.6/5, at $49.79; the Xiaomi Sound Party ranks #20, rated 4.1/5, and costs $149.99, which makes this an easy call rather than a real tradeoff.
The Xiaomi Sound Party is the longer-running pick. A versatile outdoor speaker with warm, balanced sound, fully waterproof build, long battery life, a phone charging port and a handy retractable handle. It is rated for 26 hours of battery against 16 for the EarFun Uboom L. It links with other speakers (Party Connect, up to 100 speakers), which the EarFun Uboom L cannot. The tradeoff: The sound evidence is mixed rather than universally glowing.
The EarFun Uboom L is the better-sounding, lighter option. A great value medium speaker with clear, natural sound, waterproofing, and a Video Mode that keeps audio in sync with video. At 1.4 lbs (650 g) it weighs much less than the Xiaomi Sound Party at 2.6 lbs (1.2 kg). It supports AAC Bluetooth, which the Xiaomi Sound Party lacks. It keeps a wired aux input, which the Xiaomi Sound Party lacks. Watch for: It cannot produce real low-bass rumble or fill a large, noisy space, and the top end loses some detail.
Buy the EarFun Uboom L. It is rated higher for sound quality than the Xiaomi Sound Party and costs less, which makes it the one to get unless you need something the other one does better.
