Short answer: the Xiaomi Sound Party. It ranks #19 of 157 medium speakers by sound quality (rated 4.1/5); the Boat Stone 350 ranks #135 (rated 2.3/5).
The Xiaomi Sound Party is the better-sounding, deeper-bass choice. An unusually versatile 2.6 lbs (1.2 kg) outdoor speaker: IP67 dust/water protection, USB-C power-bank output, NFC pairing, lights, stereo pairing and a claimed 26-hour battery life. Its bass reaches about 54Hz before falling 10dB, against 87Hz for the Boat Stone 350. It is rated for 26 hours of battery against 6 for the Boat Stone 350. The catch: The sound evidence is mixed rather than universally glowing.
The Boat Stone 350 is the lighter choice. 10W cylindrical stereo speaker with dual passive radiators, IPX7 water resistance, microSD card slot, and 3.5mm aux input. At 0.9 lbs (426 g) it weighs much less than the Xiaomi Sound Party at 2.6 lbs (1.2 kg). It keeps a wired aux input, which the Xiaomi Sound Party lacks. It plays in stereo from a single unit, unlike the Xiaomi Sound Party. The catch: Midrange peaks with rolled-off treble.
Buy the Xiaomi Sound Party. It is rated higher for sound quality than the Boat Stone 350.

The Two Speakers In Full
Xiaomi Sound Party: $142.99 Amazon eBay
Pros: An unusually versatile 1.2kg outdoor speaker: IP67 dust/water protection, USB-C power-bank output, NFC pairing, lights, stereo pairing and a claimed 26-hour battery life. Several independent reviews describe a warm, generally balanced sound with clear vocals and useful bass impact when Bass Boost is off. It is also easy to carry thanks to the retractable handle. Measured bass extension of 54Hz (-10dB).
Cons: The sound evidence is mixed rather than universally glowing. One lab review found it loud but flat and unclean with blurred treble, while others hear the Bass Boost mode as boomy upper bass that can bottom out at high volume. It is not the strongest choice for a large party: tested output is around 94dB and rivals such as the Soundcore Boom 2 play louder with deeper bass. SBC is the only Bluetooth codec and there is no aux input.
