These are not really the same size class, and that is the honest framing here. The JBL Xtreme 3 ranks #18 of 120 large speakers by sound quality at $269.95; the Xiaomi Sound Party ranks #20 of 179 medium speakers by sound quality at $135.84.
The JBL Xtreme 3 is the louder option. A loud, waterproof stereo speaker with deep bass, balanced sound and a power bank for charging devices. Alan Ross Reviews measured it at 105dB at full volume, against 102dB for the Xiaomi Sound Party. It keeps a wired aux input, which the Xiaomi Sound Party lacks. It plays in stereo from a single unit, unlike the Xiaomi Sound Party. The tradeoff: Boosted bass.
The Xiaomi Sound Party is the longer-running, lighter 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 15 for the JBL Xtreme 3. At 2.6 lbs (1.2 kg) it weighs noticeably less than the JBL Xtreme 3 at 4 lbs (1.83 kg). It has an adjustable EQ, which the JBL Xtreme 3 lacks. Watch for: The sound evidence is mixed rather than universally glowing.
Buy the JBL Xtreme 3 at $269.95 if you want a large speaker. Buy the Xiaomi Sound Party at $135.84 if you want a medium speaker instead.
