Short answer: the Xiaomi Sound Outdoor, if you are buying new. The Bogasing M4 ranks higher than it (#28 vs #47 of 164 medium speakers, 4.0/5 vs 3.7/5) but is discontinued, so only consider it used; the Xiaomi Sound Outdoor is still sold new at $54.99.
The Bogasing M4 is the longer-running pick. Super Bass mode gives the most balanced sound. It is rated for 24 hours of battery against 12 for the Xiaomi Sound Outdoor. It keeps a wired aux input, which the Xiaomi Sound Outdoor lacks. It plays in stereo from a single unit, unlike the Xiaomi Sound Outdoor. The catch: It sounds a bit harsh and thin.
What the Xiaomi Sound Outdoor does well: Xiaomi Sound Outdoor uses 20W woofer, 10W tweeter + 2x passive radiators. The tradeoff: Its 60Hz to 20kHz (Manufacturer specified) specification points to limited deep-bass reach for the cabinet size.
Buy the Xiaomi Sound Outdoor new; the Bogasing M4 is no longer sold new, so it only makes sense as a used find.
