Short answer: the Soundcore Boost “upgraded” 2021. It ranks #4 of 136 medium speakers by sound quality at $60; the Harman Kardon Luna ranks #22 and costs $290.99, so there is little reason to consider the other one.
What the Soundcore Boost “upgraded” 2021 offers: A very neutral good sounding inexpensive small speaker with quite deep bass for the size. This upgraded version has a usb-c port while the old one has micro usb. Watch for: Slight DSP tuning issue which makes bass get lighter at times at very low volumes, examples in oluv’s video.
What the Harman Kardon Luna offers: Pretty balanced sound besides the boosted bass. Watch for: Not stereo. Boosted bass, not as detailed as higher ranked speakers
Buy the Soundcore Boost “upgraded” 2021. It ranks higher for sound quality than the Harman Kardon Luna and costs less, so there is no real case for the other one.
