Short answer: the Sony ULT Field 5. It ranks #44 of 82 large speakers by sound quality, rated 3.5/5, at $198. The LG Xboom XG7 ranks #74, rated 2.4/5, at $120, $78 cheaper, which does not close the gap in sound quality.
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. The tradeoff: 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 LG Xboom XG7: Impressive 24-hour battery life. The catch: Peaky midrange, rolled off treble.
Buy the Sony ULT Field 5. It is rated higher for sound quality, and the $78 saving on the LG Xboom XG7 is not enough to make up the difference.

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.
