Short answer: the Xiaomi Sound Outdoor. It ranks #47 of 164 medium speakers by sound quality (rated 3.7/5) at $54.99 and is still sold new; the Sony XB23 ranks #83 (rated 3.3/5) and is discontinued, so it is only an option used.
The Xiaomi Sound Outdoor is the better-sounding, tougher choice. A decent sounding speaker for its size. It is rated IP67 against IPX4 for the Sony XB23. The catch: Boosted bass that gets somewhat uncontrolled at high levels.
Why pick the Sony XB23: Reasonably neutral. It has an adjustable EQ, which the Xiaomi Sound Outdoor lacks. It plays in stereo from a single unit, unlike the Xiaomi Sound Outdoor. The catch: Bass drops off a ton at high levels.
Buy the Xiaomi Sound Outdoor. It is rated higher for sound quality, and the Sony XB23 is discontinued, so it is only available used.

The Two Speakers In Full
Xiaomi Sound Outdoor: $54.99 Amazon eBay
Pros: Xiaomi Sound Outdoor uses 20W woofer, 10W tweeter + 2x passive radiators. Its 597 g, claimed 12 hours (Manufacturer specified) battery life, IP67 protection and mono playback make it a practical option for its intended room or portable use. A decent sounding speaker for its size.
Cons: Its 60Hz to 20kHz (Manufacturer specified) specification points to limited deep-bass reach for the cabinet size. There is no companion app. No EQ adjustment. Boosted bass that gets somewhat uncontrolled at high levels.
