Short answer: the Marshall Middleton. It ranks #33 of 120 large speakers by sound quality (rated 4.0/5) at $257.52 and is still sold new; the LG PN7 ranks #95 (rated 2.7/5) and is discontinued, so it is only an option used.
The Marshall Middleton is the better-sounding option. A waterproof stereo speaker with very deep bass for its size, a long battery, a power bank and a detachable strap. It links with other speakers (Marshall Stack), which the LG PN7 cannot. The catch: 5db dip at 1.7kHz and 6.3kHz.
The LG PN7 is the louder choice. A waterproof stereo speaker with a long battery, loud maximum volume, and party linking with other LG speakers, now discontinued. Alan Ross Reviews measured it at 106dB at full volume, against 99dB for the Marshall Middleton. The catch: The two 63mm woofers cannot produce deep bass, so it sounds thin for its size.
Buy the Marshall Middleton. It is rated higher for sound quality and still sold new, while the LG PN7 is discontinued.
