Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The Xiaomi Sound Party ranks #19 of 144 medium speakers by sound quality at $133.62; the Sony ULT Field 5 ranks #44 of 82 large speakers by sound quality at $198.
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. The tradeoff: The sound evidence is mixed rather than universally glowing.
Why pick the Sony ULT Field 5: A tough 3.3kg portable with IP67 protection, LDAC/AAC support, aux input, a 10-band app EQ, Party Connect, USB-C power-bank output and a claimed 25-hour battery. The tradeoff: It prioritizes bass and loudness over fidelity: reviews find the upper mids and highs subdued, with limited stereo separation and soundstage depth.
Buy the Xiaomi Sound Party at $133.62 if you want a medium speaker. Buy the Sony ULT Field 5 at $198 if you want a large speaker instead.

The Two Speakers In Full
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.

Sony ULT Field 5: $198 Amazon eBay
Older models: the Sony SRS-XB43 (rated 3.5/5) and the Sony SRS-XG300 (rated 3.1/5).
Pros: A tough 3.3kg portable with IP67 protection, LDAC/AAC support, aux input, a 10-band app EQ, Party Connect, USB-C power-bank output and a claimed 25-hour battery. Reviews find it energetic and dynamic with substantial bass, enough volume for a yard, and two ULT modes that let bass-focused listeners choose a deeper or punchier presentation.
Cons: It prioritizes bass and loudness over fidelity: reviews find the upper mids and highs subdued, with limited stereo separation and soundstage depth. Deep bass is less authoritative than the enclosure suggests, and the loud confirmation tone when pressing the ULT button is an unnecessary annoyance. Use the app EQ and audition it before buying for detail-focused music.
