Short answer: the JBL Flip 7. It ranks #15 of 172 medium speakers at $89.95; the Harman Kardon Luna 2 ranks #25 at $199.95, so there isn’t much of a tradeoff to weigh.
The Flip 7 is a very neutral, pocket-size speaker with only minor tuning shifts. It has just slightly more treble and slightly deeper bass than the well-regarded Flip 6, though a small bump at 4kHz makes it not quite as neutral as its predecessor.
The Luna 2 makes a real case on midrange articulation, with tradeoffs. Its imaging and instrument separation are described as precise and spacious, and its 62mm x 82mm woofer and passive radiator deliver tight, well-controlled bass that stays cleaner at volume than pricier rivals like the Sonos Play. It is also IP67 rated and can pair two units via AirTouch for true stereo. But the treble can sound bright and edgy, it loses more output off-axis than some rivals, some listeners hear mid-range rattling on certain tracks, and its 12-hour battery life trails category leaders like the JBL Charge 6, which doubles it.
What the Luna 2 adds: true stereo pairing via AirTouch and a larger woofer, both absent on the single-driver Flip 7.
What the Flip 7 adds: Auracast party mode, a 100dB max volume rating, and a higher IP68 rating, all missing from the Luna 2.
Buy the JBL Flip 7 for its very neutral tuning, small pocket-size body, and lower price.
Buy the Harman Kardon Luna 2 if true stereo pairing and a more spacious midrange matter more to you than battery life or price.
