Short answer: the Bogasing G4. It ranks #27 of 177 medium speakers by sound quality, rated 4.0/5, at $42.49; the Bogasing M5 ranks #61, rated 3.5/5, and costs $52.99, so there is little reason to consider the other one.
The G4 is the better Bogasing. Two drivers and passive radiators on 50W play in stereo, Alan Ross measured 100dB, and its bass reaches about 56Hz before falling 10dB. It claims 24 hours of battery and supports LE Audio with LC3. Its upper treble is boosted and uneven, and it has no app or EQ.
The M5 is smaller, with a longer battery. It claims 30 hours, fits a backpack side pocket at 1.7 lbs (757 g) and has an aux input. Its front and rear drivers sound thin in the midrange with hot treble by default. Use its bass mode for the flattest response.
Buy the Bogasing G4. It is rated higher for sound quality than the Bogasing M5 and costs less, which makes it the one to get unless you need something the other one does better.
