Short answer: the Sony ULT Field 5. It ranks #44 of 82 large speakers by sound quality, rated 3.5/5, at $198. The Tronsmart Halo 100 ranks #54, rated 3.2/5, at $109.99, $88.01 cheaper, a saving that is not big enough to make up the sound-quality gap.
What the Sony ULT Field 5 does well: 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. Watch for: It prioritizes bass and loudness over fidelity: reviews find the upper mids and highs subdued, with limited stereo separation and soundstage depth.
Why pick the Tronsmart Halo 100: 60W power with excellent bass (tested 100dB), IPX6 waterproof design, RGB LED party lights, 18 hours battery without lights, 6000mAh capacity with USB-A charging port for devices, good value outdoor party speaker. The tradeoff: Not a very smooth frequency response.
Buy the Sony ULT Field 5. It is rated higher for sound quality, and the $88.01 you would save on the Tronsmart Halo 100 does not close the gap.

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.
