Short answer: the Soundcore Boost “upgraded” 2021 ranks #4 of 136 medium speakers by sound quality at $60; the Ultimate Ears Wonderboom 4 ranks #84 at $59.99. With prices this close, go by the sound-quality ranking rather than the cost.
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 Ultimate Ears Wonderboom 4 offers: Small size. Watch for: Bass isn’t as deep as the top-ranked speakers and is a little thuddy. Not much improvement over the previous Ultimate Ears Wonderboom 3 besides the USB-C charging port.
Buy the Soundcore Boost “upgraded” 2021 when sound quality outweighs the price for you, and the Ultimate Ears Wonderboom 4 when the price outweighs sound quality instead.
