Short answer: the Sony ULT Field 5. It ranks #59 of 120 large speakers by sound quality (rated 3.5/5) at $348 and is still sold new; the LG Xboom XG7 ranks #105 (rated 2.4/5) and is discontinued, so it is only an option used. The LG Xboom XG7’s replacement, the LG Xboom Bounce, is rated 3.6/5 at $149.99.
The Sony ULT Field 5 is the better-sounding option. A tough, waterproof party speaker with loud, bass focused output, an aux input, a power bank and a long battery. It supports LDAC Bluetooth, which the LG Xboom XG7 lacks. It has an adjustable EQ, which the LG Xboom XG7 lacks. The catch: 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: A waterproof party speaker with customizable LED lights, a long battery, and party linking with other LG speakers, now discontinued. The catch: Peaky midrange, rolled off treble.
Buy the Sony ULT Field 5. It is rated higher for sound quality; the LG Xboom XG7 is no longer sold new.
