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 Go PL7 ranks #75, rated 2.4/5, at $70, $128 cheaper, which does not close the gap in sound quality.
The case for 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.
The case for the LG Xboom Go PL7: A 1.45kg portable with IPX7 protection, a claimed 24-hour battery, aux input, speakerphone capability, stereo pairing and Wireless Party Link. The tradeoff: Independent testing finds weak low-bass and top-end extension, a narrow soundstage and uneven off-axis response.
Buy the Sony ULT Field 5. It is rated higher for sound quality, and the $128 saving on the LG Xboom Go PL7 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.

LG Xboom Go PL7: $70 LG eBay
Pros: A 1.45kg portable with IPX7 protection, a claimed 24-hour battery, aux input, speakerphone capability, stereo pairing and Wireless Party Link. It plays fairly loudly for its size with few obvious artifacts, and its LED-rimmed passive radiators make it a practical, fun choice for casual outdoor listening.
Cons: Independent testing finds weak low-bass and top-end extension, a narrow soundstage and uneven off-axis response. The default Sound Boost processing can make the upper mids and treble aggressive; turning it off improves balance but does not transform it into a detailed or deep-bass speaker. It has no user EQ to properly tailor the result.
