Short answer: the Harman Kardon Luna, if you are buying new. The Soundcore Boost “original model” pre-2021 ranks higher than it (#14 vs #26 of 175 medium speakers, 4.2/5 vs 4.0/5) but is discontinued, so only consider it used; the Harman Kardon Luna is still sold new at $290.99.
The Soundcore Boost “original model” pre-2021 is the lighter option. At 1.3 lbs (590 g), Soundcore Boost “original model” pre-2021 combines 1.75” x 2 active drivers + passive radiator with Bluetooth and aux. At 1.3 lbs (590 g) it weighs much less than the Harman Kardon Luna at 2.5 lbs (1.13 kg). It keeps a wired aux input, which the Harman Kardon Luna lacks. It has an adjustable EQ, which the Harman Kardon Luna lacks. The tradeoff: Careful placement is still important for balanced bass.
The Harman Kardon Luna is the tougher option. The sound is fairly balanced apart from the boosted bass. It is rated IP67 against IPX5 for the Soundcore Boost “original model” pre-2021. It charges over USB-C rather than Micro USB. The tradeoff: Boosted bass, and less detailed than higher-ranked speakers.
Buy the Harman Kardon Luna new; the Soundcore Boost “original model” pre-2021 is no longer sold new, so it only makes sense as a used find.
