Short answer: the JBL Flip 6. It ranks #12 of 138 medium speakers by sound quality at $114.95; the Harman Kardon Luna 2 ranks #22 and costs $199.95, so there is little reason to consider the other one.
What the Harman Kardon Luna 2 offers: 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. The catch: 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.
What the JBL Flip 6 gets right: A very neutral speaker, very small, almost pocket size, a huge sound quality leap over the Flip 5. The tradeoff: Not stereo. Some slight upper mids emphasis. The TL version (made in Vietnam) tweeter can sound somewhat scratchy and doesn’t sound as good as the GG version (made in China)
Buy the JBL Flip 6. It ranks higher for sound quality than the Harman Kardon Luna 2 and costs less, so the other one has nothing left to offer.

Harman Kardon Luna 2: $199.95 Amazon B&H Photo Video eBay
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).
