These sit in different size classes, so this is not a straight ranking comparison. The Xiaomi Sound Outdoor ranks #46 of 179 medium speakers by sound quality at $49.99; the JBL Go 4 ranks #30 of 62 small speakers by sound quality at $49.95.
The Xiaomi Sound Outdoor is the longer-running choice. An affordable waterproof outdoor speaker with a separate tweeter, decent battery life and linking to many more speakers. It is rated for 12 hours of battery against 7 for the JBL Go 4. The catch: Bass reach is limited for the cabinet size, with a rated lower limit of 60Hz, and the boosted bass gets somewhat uncontrolled at high levels.
The JBL Go 4 is the lighter choice. A pocket sized waterproof mini speaker with a loop for hanging and app EQ. At 0.4 lbs (190 g) it weighs much less than the Xiaomi Sound Outdoor at 1.3 lbs (597 g). It has an adjustable EQ, which the Xiaomi Sound Outdoor lacks. The tradeoff: Not much bass at all, especially with electronic/bass-heavy tracks pushed past ~50% volume.
Buy the Xiaomi Sound Outdoor at $49.99 for a medium speaker, or the JBL Go 4 at $49.95 for a small speaker instead.
