Short answer: the Marshall Stockwell III. It ranks #84 of 120 large speakers by sound quality (rated 3.0/5) at $249.99 and is still sold new; the LG Xboom Go PL7 ranks #106 (rated 2.4/5) and is discontinued, so it is only an option used.
The Marshall Stockwell III is the better-sounding, longer-running pick. A stylish, rugged speaker with a very long battery you can swap yourself, a detailed app EQ, and power bank charging. It is rated for 40 hours of battery against 24 for the LG Xboom Go PL7. It supports AAC Bluetooth, which the LG Xboom Go PL7 lacks. It has an adjustable EQ, which the LG Xboom Go PL7 lacks. The catch: Highs are recessed by default and need the treble control maxed to compensate, still lacking detail even then.
The LG Xboom Go PL7 is the tougher choice. A fun, waterproof portable with glowing light rings, a long battery, and stereo pairing for casual outdoor listening, now discontinued. It is rated IPX7 against IP55 for the Marshall Stockwell III. The catch: Independent testing finds weak low-bass and top-end extension, a narrow soundstage and uneven off-axis response.
Buy the Marshall Stockwell III. It is rated higher for sound quality, and the LG Xboom Go PL7 is discontinued, so it is only available used.
