Short answer: both are discontinued, so this only matters if you are buying used. Used, the Bogasing M4 is the better pick: it ranks #28 of 166 medium speakers by sound quality (rated 4.0/5), against #54 (rated 3.6/5) for the Tronsmart Element Force. If you want one new, the Bogasing M5 replaces the Bogasing M4 and is rated 3.5/5 at $52.99.
The Bogasing M4 is the better-sounding, deeper-bass choice. Super Bass mode gives the most balanced sound. Its bass reaches about 54Hz before falling 10dB, against 63Hz for the Tronsmart Element Force. It is rated for 24 hours of battery against 15 for the Tronsmart Element Force. Watch for: It sounds a bit harsh and thin.
The case for the Tronsmart Element Force: Great value with high-end features for the price: IPX7 rated, USB-C charging, microSD support. It has an adjustable EQ, which the Bogasing M4 lacks. Watch for: Not as deep of bass as others.
Buy the Bogasing M4 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.
