Short answer: the Boost upgraded, with the Motion 300 close behind. The Boost at $60 is a very neutral, good sounding small speaker with quite deep bass for its size, though a slight DSP issue can lighten the bass at very low volumes. The Motion 300 costs $79.99 and has pretty deep bass for its small size, but the notes say it is lacking without EQ or the top two treble EQ bars maxed.
Buy the Soundcore Motion 300. It is rated higher for sound quality; the Soundcore Boost “upgraded” 2021 is no longer sold new.
