Short answer: the Harman Kardon Luna. It ranks #26 of 175 medium speakers by sound quality (rated 4.0/5) at $290.99 and is still sold new; the Soundcore Flare 2 ranks #134 (rated 2.6/5) and is discontinued, so it is only an option used.
The Harman Kardon Luna is the better-sounding choice. The sound is fairly balanced apart from the boosted bass. The catch: Boosted bass, and less detailed than higher-ranked speakers.
The Soundcore Flare 2 is the lighter option. Try Alan Ross’s EQ for it. At 1.3 lbs (600 g) it weighs much less than the Harman Kardon Luna at 2.5 lbs (1.13 kg). It has an adjustable EQ, which the Harman Kardon Luna lacks. It plays in stereo from a single unit, unlike the Harman Kardon Luna. The tradeoff: Rolled off treble.
Buy the Harman Kardon Luna. It is rated higher for sound quality and still sold new, while the Soundcore Flare 2 is discontinued.
