Short answer: the Harman Kardon Luna 2. It ranks #23 of 150 medium speakers by sound quality, rated 4.1/5, at $199.95. The LG Xboom Go PL5 ranks #125, rated 2.4/5, at $179, $20.95 cheaper, not enough of a saving to outweigh the sound-quality gap.
What the Harman Kardon Luna 2 does well: Articulate, spacious midrange with precise imaging and instrument separation. The tradeoff: Treble can sound bright and edgy, and it loses more output off-axis than some rivals.
What the LG Xboom Go PL5 does well: 18 hour battery life; IPX5 rated. The catch: Barely any bass.
Buy the Harman Kardon Luna 2. It is rated higher for sound quality, and saving $20.95 with the LG Xboom Go PL5 does not make up for the sound-quality gap.

Harman Kardon Luna 2: $199.95 Amazon B&H Photo Video eBay
Older model: the Harman Kardon Luna (ranked lower, rated 4/5).
Pros: Articulate, spacious midrange with precise imaging and instrument separation. Tight, well-controlled bass from the 62mm x 82mm woofer and passive radiator despite the compact body, and it stays cleaner at volume than pricier rivals like the Sonos Play. IP67 rated, and two units pair via AirTouch for true stereo sound.
Cons: Treble can sound bright and edgy, and it loses more output off-axis than some rivals. Some listeners hear mid-range rattling on certain tracks, similar to sibling JBL models. 12-hour battery life trails category leaders like the JBL Charge 6, which doubles it. Single unit is not stereo (1.1 driver layout).
