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 Soundcore Select 4 Go ranks #25 of 62 small speakers by sound quality at $22.99.
What the Xiaomi Sound Outdoor does well: An affordable waterproof outdoor speaker with a separate tweeter, decent battery life and linking to many more speakers. It links with other speakers (Speakersync, up to 100 speakers), which the Soundcore Select 4 Go cannot. 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 Soundcore Select 4 Go is the longer-running, lighter choice. A very inexpensive waterproof mini speaker with a strap, a long battery, app EQ, and stereo pairing. It is rated for 20 hours of battery against 12 for the Xiaomi Sound Outdoor. At 0.6 lbs (265 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. Watch for: Not as deep of bass as higher ranked speakers.
Buy the Xiaomi Sound Outdoor at $49.99 for a medium speaker, or the Soundcore Select 4 Go at $22.99 for a small speaker instead.
