Short answer: the Soundcore Boom Go 3i. It ranks #2 of 62 small speakers by sound quality, rated 4.4/5, at $59.99. The Sony SRS-XB100 ranks #43, rated 2.9/5, at $44, $15.99 cheaper, which does not close the gap in sound quality.
The Soundcore Boom Go 3i is the better-sounding, longer-running option. An exceptionally rugged 0.8 lbs (380 g) 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 is rated for 24 hours of battery against 16 for the Sony SRS-XB100. It links with other speakers (Auracast), which the Sony SRS-XB100 cannot. It has an adjustable EQ, which the Sony SRS-XB100 lacks. Watch for: 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.
The Sony SRS-XB100 is the lighter option. Long real-world battery life (~17 hours in testing). At 0.6 lbs (274 g) it weighs noticeably less than the Soundcore Boom Go 3i at 0.8 lbs (380 g). It supports AAC Bluetooth, which the Soundcore Boom Go 3i lacks. The tradeoff: Not much bass.
Buy the Soundcore Boom Go 3i. It is rated higher for sound quality, and the $15.99 you would save on the Sony SRS-XB100 does not close the gap.

The Two Speakers In Full
Soundcore Boom Go 3i: $59.99 Amazon $59.99 AliExpress $133.27 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

Sony SRS-XB100: $44.00 Amazon $44.00 eBay
Older models: the Sony SRS-XB13 (ranked lower, rated 2.8/5) and the Sony SRS-XB12 (ranked lower, rated 2.5/5). See every Sony XB compact generation.
Pros: Long real-world battery life (~17 hours in testing). IP67 rated and pocketable at 267g, with a clip for bags/gear. Can stereo-pair two units.
Cons: Not much bass. Seems pretty much the same as the XB13, maybe a teeny bit deeper bass and a little less muddy.
