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 166 medium speakers by sound quality (rated 4.4/5), against #28 (rated 4.0/5) for the Bogasing M4. If you want one new, the Bogasing M5 replaces the Bogasing M4 and is rated 3.5/5 at $52.99.
The Soundcore Boost “upgraded” 2021 is the better-sounding choice. A very neutral good sounding inexpensive small speaker with quite deep bass for the size. It has an adjustable EQ, which the Bogasing M4 lacks. The catch: Slight DSP tuning issue which makes bass get lighter at times at very low volumes, examples in oluv’s video.
The Bogasing M4 is the longer-running choice. Super Bass mode gives the most balanced sound. It is rated for 24 hours of battery against 12 for the Soundcore Boost “upgraded” 2021. It keeps a wired aux input, which the Soundcore Boost “upgraded” 2021 lacks. The tradeoff: It sounds a bit harsh and thin.
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, buy the Bogasing M5, which replaces the Bogasing M4.

Bogasing M4: $45.99 Discontinued eBay
Newer model: the Bogasing M5, ranked lower, rated 3.5/5, released Dec 2022. It adds adjustable EQ. Battery life goes from 24 to 30 hours. See every Bogasing M generation.
Pros: Bogasing M4 uses 52mm speaker unit. Its 731 g, claimed 24 hours (Manufacturer specified) battery life, IPX7 protection, aux input, up to 99dB and stereo playback make it a practical option for its intended room or portable use. Super Bass mode gives the most balanced sound. Measured bass extension of 54Hz (-10dB).
Cons: Bass is limited by its 54Hz specification. There is no companion app. No EQ adjustment. It sounds a bit harsh and thin. Discontinued.
