Short answer: the Xiaomi Sound Party. It ranks #19 of 150 medium speakers by sound quality, rated 4.1/5, at $142.99. The Bose Soundlink Flex ranks #36, rated 3.8/5, at $79.99, $63 cheaper, which does not close the gap in sound quality.
What the Xiaomi Sound Party does well: 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. The tradeoff: The sound evidence is mixed rather than universally glowing.
What the Bose Soundlink Flex does well: IP67 rated; rugged enough to survive drops from several feet and floats. Watch for: Not stereo.
Buy the Xiaomi Sound Party. It is rated higher for sound quality, and saving $63 with the Bose Soundlink Flex does not make up for the sound-quality gap.
If battery life is a priority, the Xiaomi Sound Party is rated for 26 hours versus 12 hours for the Bose Soundlink Flex.

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.
