Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The Harman Kardon Luna 2 ranks #25 of 179 medium speakers by sound quality at $199.95; the Bose Soundlink Micro 2 ranks #18 of 62 small speakers by sound quality at $129.

The case for the Harman Kardon Luna 2: A stylish waterproof speaker with clear, spacious mids, tight bass that stays clean at volume, and stereo pairing with a second unit. The tradeoff: Treble can sound bright and edgy, and it loses more output off-axis than some rivals.
The Bose Soundlink Micro 2 is the lighter option. A waterproof mini speaker with a fabric strap for bags and bikes and USB-C charging. At 0.7 lbs (329 g) it weighs much less than the Harman Kardon Luna 2 at 1.6 lbs (735 g). It supports aptX Bluetooth, which the Harman Kardon Luna 2 lacks. The tradeoff: Lack of clarity.
Buy the Harman Kardon Luna 2 at $199.95 for a medium speaker, or the Bose Soundlink Micro 2 at $129 for a small speaker instead.
