Short answer: the Teufel Boomster Go for balanced sound, the Boom Go 3i for battery and durability. The Teufel is pretty deep and quite balanced overall for its size, though distortion becomes audible above roughly 75% volume and it turns unclear and tinny at max volume up close. The Boom Go 3i runs about 24 hours, is IP68 rated and carries a music-synced RGB light strip, but sounds a bit piercing and metallic with a peak at 10kHz.
What the Soundcore Boom Go 3i offers: IP68 rated (full submersion + dustproof). ~24 hour battery life. RGB light strip syncs to the music. The tradeoff: Sounds a bit piercing and metallic. Bass knocks a little bit. Peak at 10kHz.
Buy the Soundcore Boom Go 3i. It is rated higher for sound quality and still sold new, while the Teufel Boomster Go is discontinued.

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
