Short answer: the Soundcore Boom Go 3i for waterproofing, the Minirig Mini for balance. The Mini is very neutral, but it calls itself splash resistant with no official water rating. The Boom Go 3i is IP68 rated for full submersion and dustproofing and costs $40.01 less, though it sounds a bit piercing and metallic.
The case for the Minirig Mini: Very neutral. Set against that: Calls itself splash resistant and has no official water rating.
What the Soundcore Boom Go 3i gets right: IP68 rated (full submersion + dustproof). The catch: Sounds a bit piercing and metallic.
One note: the Minirig Mini is no longer sold new, but at #4 of 47 small speakers by sound quality it still outranks most current models, so used is worth considering.
Buy the Soundcore Boom Go 3i. It is rated higher for sound quality than the Minirig Mini and costs less, so there is no real case for the other one.
If battery life is a priority, the Soundcore Boom Go 3i is rated for 24 hours versus 10 hours for the Minirig Mini.

Soundcore Boom Go 3i: $59.99 Amazon Aliexpress eBay
Pros: An exceptionally rugged 380g mini speaker with IP68 protection, a floating sound-forward design, app EQ, RGB lighting, a battery display, USB-C power-bank output and Auracast/TWS linking. It reaches about 92dB and independent testing finds it lasts nearly six hours at maximum volume with lights and BassUp enabled, matching its demanding claim.
Cons: This is still a 15W mono speaker: bass impact and stereo width are limited, and critical listeners may find the upper treble piercing or metallic. It is directional by design, so the sound changes off-axis, and independent reviews note it lacks a built-in microphone; it is far better for rugged outdoor background music than a large gathering.
Setup: Try out Oluv’s EQ which slightly improves the sound
