Short answer: choose the Soundcore Boom Go 3i for rugged outdoor use, or the Marshall Willen for clearer vocals in a smaller package. The Boom Go 3i has the more serious IP68 build and is intended for rougher use, whereas the Willen concentrates on midrange clarity rather than low-end weight.
Neither is a true bass speaker. The Boom Go 3i can sound metallic or piercing, so its resilience is its main appeal. The Willen is a more natural fit for podcasts and vocal music, though its small enclosure cannot deliver much deep bass.
On the Soundcore Boom Go 3i side: IP68 rated (full submersion + dustproof). Set against that: Sounds a bit piercing and metallic.
Buy the Soundcore Boom Go 3i if dustproof, submersible portability is more important than tonal refinement.
Buy the Marshall Willen if you want the clearer vocal presentation in the smallest everyday speaker.
If battery life is a priority, the Soundcore Boom Go 3i is rated for 24 hours versus 15 hours for the Marshall Willen.

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
