Short answer: the Marshall Stockwell III. It ranks #59 of 82 large speakers by sound quality, rated 3.0/5, at $249.99. The LG PN7 ranks #68, rated 2.7/5, at $150, $99.99 cheaper, which does not close the gap in sound quality.
Why pick the Marshall Stockwell III: 40+ hour battery life with a user-replaceable battery, strap, sleeve and grilles. The tradeoff: Highs are recessed by default and need the treble control maxed to compensate, still lacking detail even then.
What the LG PN7 does well: Exceptional 24-hour battery life, IPX7 waterproof, 106dB max volume, XBOOM remote app support, Wireless Party Link feature, stereo capable, USB-C charging, built-in microphone. The tradeoff: No deep bass.
Buy the Marshall Stockwell III. It is rated higher for sound quality, and the $99.99 you would save on the LG PN7 does not close the gap.

The Two Speakers In Full
Marshall Stockwell III: $249.99 Marshall eBay
Older model: the Marshall Stockwell II (rated 4.5/5).
Pros: 40+ hour battery life with a user-replaceable battery, strap, sleeve and grilles. Doubles as a USB-C power bank. IP55 dust/water resistance. App includes parametric EQ, a Soundstage widening control, and wall/corner placement compensation. Endless-rotation control knobs.
Cons: Highs are recessed by default and need the treble control maxed to compensate, still lacking detail even then. Bass tends to sound resonant and boomy, with reported frequency cancellation and phase issues on complex material that EQ doesn’t fully resolve. Oluv’s A/B testing against the outgoing Stockwell II finds the default tuning muffled and muddy enough to prefer the seven-year-old original out of the box, and output loses dynamics and bass while turning harsh well below maximum volume. No aptX support.
