Short answer: the Soundcore Boost “upgraded” 2021. It ranks #4 of 136 medium speakers by sound quality at $60; the KEF Muo gen2 ranks #73 and costs $249.99, which makes this an easy call rather than a real tradeoff.
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 KEF Muo gen2 offers: KEF seemed to have fixed the rolled off treble and overall balance Watch for: Lacking deeper bass. Very thuddy bass. Appears to be the exact same hardware but with updated tuning. Bass distorts as volume increases, and the claimed 43Hz extension is really only audible at low listening volumes, with a few seconds of lag after volume changes. Loses most of its bass off-axis. Customer reviews are mixed, ranging from praise for detail at low volume to complaints of a boxy, hollow sound.
Buy the Soundcore Boost “upgraded” 2021. It ranks higher for sound quality than the KEF Muo gen2 and costs less, which settles it without a real tradeoff to make.
If battery life is a priority, the KEF Muo gen2 is rated for 24 hours versus 12 hours for the Soundcore Boost “upgraded” 2021.
