Short answer: the LG PN7, because the Sony’s bass is shallow and its sound merely okay. The ULT Field 5 at $198 against $150 is IP67 rated, dustproof and water resistant, but its bass is not as deep as others in the category and sound quality overall is just okay. The PN7 counters with a 24-hour battery, IPX7 waterproofing, 106dB max volume, XBOOM app support, Wireless Party Link and stereo capability, though it also lacks deep bass.
What the LG PN7 gets right: Exceptional 24-hour battery life, IPX7 waterproof, 106dB max volume, XBOOM remote app support, Wireless Party Link feature, stereo capable. The tradeoff: No deep bass.
On the Sony ULT Field 5 side: IP67 rated, dustproof and water resistant. The catch: Bass not as deep as others in the category, and sound quality overall is just okay.
Buy the LG PN7 when the price outweighs sound quality for you, and the Sony ULT Field 5 when sound quality outweighs the price instead.
The LG PN7 is not a sound-quality pick. It sits near the bottom of the 78 large speakers; there are better options higher up.

Sony ULT Field 5: $198 Amazon eBay
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.
