These are not really the same size class, and that is the honest framing here. The Harman Kardon Luna 2 ranks #23 of 144 medium speakers by sound quality at $199.95; the Bose Soundlink Micro ranks #19 of 47 small speakers by sound quality at $83.99.
Why pick the Harman Kardon Luna 2: Articulate, spacious midrange with precise imaging and instrument separation. The catch: Treble can sound bright and edgy, and it loses more output off-axis than some rivals.
The case for the Bose Soundlink Micro: Bose Soundlink Micro uses 40mm with dual passive radiators. The catch: Bass is limited by its 66Hz specification.
Buy the Harman Kardon Luna 2 at $199.95 if you want a medium speaker. Buy the Bose Soundlink Micro at $83.99 if you want a small speaker instead.
Battery life favors the Harman Kardon Luna 2: rated for 12 hours against 6 hours for the Bose Soundlink Micro.

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