Short answer: the Soundcore Boom Go 3i. It ranks #2 of 62 small speakers by sound quality (rated 4.4/5) at $59.99 and is still sold new; the Harman Kardon Neo ranks #58 (rated 2.3/5) and is discontinued, so it is only an option used.
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 10 for the Harman Kardon Neo. It is rated IP68, while the Harman Kardon Neo has no water resistance. It links with other speakers (Auracast), which the Harman Kardon Neo cannot. The tradeoff: 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 Harman Kardon Neo is the lighter pick. IPX7 waterproof, with an attachment loop and an echo-cancelling microphone for calls. At 0.6 lbs (251 g) it weighs noticeably less than the Soundcore Boom Go 3i at 0.8 lbs (380 g).
Buy the Soundcore Boom Go 3i. It is rated higher for sound quality; the Harman Kardon Neo is no longer sold new.

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
