Short answer: the LG Xboom Bounce. It ranks #33 of 115 large speakers by sound quality, rated 4.0/5, at $103.17; the Marshall Stockwell III ranks #79, rated 3.0/5, and costs $249.99, so there is little reason to consider the other one.
The Marshall Stockwell III is the longer-running choice. 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 30 for the LG Xboom Bounce. The tradeoff: Highs are recessed by default and need the treble control maxed to compensate, still lacking detail even then.
The LG Xboom Bounce is the better-sounding, tougher choice. A tough, waterproof speaker that survives drops and extreme temperatures, with a long battery and multipoint pairing. It is rated IP67 against IP55 for the Marshall Stockwell III. The tradeoff: Bass extension not as deep as the top speakers.
Buy the LG Xboom Bounce. It is rated higher for sound quality than the Marshall Stockwell III and costs less, which makes it the one to get unless you need something the other one does better.
