Short answer: the Soundcore Boom Go 3i. It ranks #2 of 47 small speakers by sound quality, rated 4.4/5, at $59.99; the Vifa City ranks #10, rated 4.0/5, and costs $139, which makes this an easy call rather than a real tradeoff.
The case for the Soundcore Boom Go 3i: 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. The catch: 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.
What the Vifa City does well: Quite detailed. The catch: Dip at 1200Hz.
Buy the Soundcore Boom Go 3i. It is rated higher for sound quality than the Vifa City and costs less, which makes it the one to get unless you need something the other one does better.
Battery life favors the Soundcore Boom Go 3i: rated for 24 hours against 12 hours for the Vifa City.
Water resistance is not close: the Soundcore Boom Go 3i is rated at IP68 (extended submersion), well ahead of the Vifa City at IPX4 (splashing).

The Two Speakers In Full
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

Vifa City: $139.00 Amazon eBay
Pros: Quite detailed. Balanced, controlled sound with clear vocals even at low volume rather than a bass-forward ‘boombox’ voicing. Two units can pair for a stereo pair. Measured bass extension of 73Hz (-10dB).
Cons: Dip at 1200Hz. Doesn’t boost bass at low levels. Not that deep of bass. Only IPX4.
