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 #125 (rated 2.7/5) for the Bose SoundLink Color II. If you want one new, the EarFun Uboom L ranks #2 at $49.79.
The Soundcore Boost “upgraded” 2021 is the better-sounding, longer-running option. A very neutral good sounding inexpensive small speaker with quite deep bass for the size. It is rated for 12 hours of battery against 8 for the Bose SoundLink Color II. It is rated IPX7 against IPX4 for the Bose SoundLink Color II. It has an adjustable EQ, which the Bose SoundLink Color II lacks. The tradeoff: Slight DSP tuning issue which makes bass get lighter at times at very low volumes, examples in oluv’s video.
What the Bose SoundLink Color II does well: Soft-touch rubber coating is comfortable to hold and tough enough for bumps and scrapes. It supports AAC Bluetooth, which the Soundcore Boost “upgraded” 2021 lacks. It links with other speakers (Bose Party mode), which the Soundcore Boost “upgraded” 2021 cannot. Watch for: Boosted bass on Color II.
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.
