Short answer: both are discontinued, so this only matters if you are buying used. Used, the Soundcore Boost “upgraded” 2021 is the better pick: it ranks #5 of 175 medium speakers by sound quality (rated 4.4/5), against #134 (rated 2.6/5) for the Soundcore Flare 2. If you want one new, the EarFun Uboom L ranks #2 at $49.79.
The Soundcore Boost “upgraded” 2021 is the better-sounding pick. A very neutral good sounding inexpensive small speaker with quite deep bass for the size. The tradeoff: Slight DSP tuning issue which makes bass get lighter at times at very low volumes, examples in oluv’s video.
What the Soundcore Flare 2 does well: Try Alan Ross’s EQ for it. It links with other speakers (PartyCast up to 100 speakers), which the Soundcore Boost “upgraded” 2021 cannot. The catch: Rolled off treble.
Buy the Soundcore Boost “upgraded” 2021 only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, start with the EarFun Uboom L instead.
