Short answer: the Xiaomi Sound Outdoor. It ranks #44 of 150 medium speakers by sound quality, rated 3.7/5, at $54.99; the Treblab HD77 ranks #87, rated 3.1/5, and costs $69.97, so there is little reason to consider the other one.
The case for the Xiaomi Sound Outdoor: Xiaomi Sound Outdoor uses 20W woofer, 10W tweeter + 2x passive radiators. The catch: Its 60Hz to 20kHz (Manufacturer specified) specification points to limited deep-bass reach for the cabinet size.
What the Treblab HD77 does well: Supports TWS pairing with a second HD77 for wider stereo sound. The catch: Lacking quite a bit of bass compared to higher ranked speakers.
Buy the Xiaomi Sound Outdoor. It is rated higher for sound quality than the Treblab HD77 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
If battery life is a priority, the Treblab HD77 is rated for 20 hours versus 12 hours for the Xiaomi Sound Outdoor.

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.
