Short answer: the JBL Flip 6 for neutrality, the Harman Kardon Luna for a fuller sound. The Luna sounds pretty balanced besides its boosted bass, but it is not stereo and that bass makes it less detailed than higher ranked speakers. The Flip 6 is very neutral and a huge sound quality leap over the Flip 5, though it is not stereo and has some slight upper mids emphasis.
In the JBL Flip 6’s favor: it’s a very neutral speaker, small enough to be almost pocket sized, and a huge sound quality leap over the Flip 5. Working against it: it’s not stereo, has some slight upper mids emphasis, and the TL version’s tweeter can sound somewhat scratchy compared to the GG version.
The pitch for the Harman Kardon Luna: it sounds pretty balanced besides the boosted bass. On the downside: it’s not stereo, and the boosted bass makes it less detailed than higher ranked speakers.
Buy the JBL Flip 6. It is rated higher for sound quality than the Harman Kardon Luna and costs less, so it is the default pick unless a specific strength of the other one matters more to you.

Harman Kardon Luna: $290.99 Amazon eBay
Newer model: the Harman Kardon Luna 2, ranked higher, rated 4.1/5.
Pros: Harman Kardon Luna uses 48mm x 90mm woofer, 20mm tweeter. Its 1.13 kg, claimed 12 hours (Manufacturer specified) battery life, IP67 protection and mono playback make it a practical option for its intended room or portable use. The sound is fairly balanced apart from the boosted bass. Measured bass extension of 57Hz (-10dB).
Cons: Bass is limited by its 57Hz specification. There is no companion app. No EQ adjustment. Boosted bass, and less detailed than higher-ranked speakers.
