Short answer: the Soundcore Boost “upgraded” 2021. It ranks #4 of 136 medium speakers by sound quality at $60; the JBL Flip 4 ranks #63 and costs $70, 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 JBL Flip 4 offers: Less bass than a Flip 5. Peaky lower treble. Watch for: Battery failures are common.
Buy the Soundcore Boost “upgraded” 2021. It ranks higher for sound quality than the JBL Flip 4 and costs less, so there is no real case for the other one.
