These are not really the same size class, and that is the honest framing here. The Marshall Stockwell II ranks #11 of 82 large speakers by sound quality at $229.99; the Xiaomi Sound Party ranks #19 of 144 medium speakers by sound quality at $133.62.
The case for the Marshall Stockwell II: Marshall Stockwell II uses 3” woofer, 2x 2” fullrange tweeters. The catch: Bass is limited by its 44Hz specification.
Why pick the Xiaomi Sound Party: 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. Watch for: The sound evidence is mixed rather than universally glowing.
Buy the Marshall Stockwell II ($229.99) for a large speaker; the Xiaomi Sound Party ($133.62) suits a medium speaker instead.
There is a real gap in water resistance: the Xiaomi Sound Party at IP67 (brief submersion) against the Marshall Stockwell II, which has IPX4 (splashing).

The Two Speakers In Full
Marshall Stockwell II: $229.99 Amazon eBay
Newer model: the Marshall Stockwell III, rated 3/5.
Pros: Marshall Stockwell II uses 3” woofer, 2x 2” fullrange tweeters. Its 1.4 kg, claimed 20 hours (Manufacturer specified) battery life, IPX4 protection, aux input, up to 96dB and mono playback make it a practical option for its intended room or portable use. Possibly the most natural sounding Marshall speaker, with excellent off-axis sound. Measured bass extension of 44Hz (-10dB).
Cons: Bass is limited by its 44Hz specification. There is no companion app. No EQ adjustment. Not very loud, and the added DSP reverb may annoy purists.

Xiaomi Sound Party: $133.62 AliExpress 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.
