Short answer: the Bogasing G4. It ranks #25 of 150 medium speakers by sound quality, rated 4.0/5, at $38.29; the JBL Charge 3 ranks #77, rated 3.2/5, and costs $80, which makes this an easy call rather than a real tradeoff.
The case for the Bogasing G4: A 0.83kg travel-friendly speaker with 50W output, IPX7 protection, USB-C charging, aux and microSD playback, LC3 Bluetooth and TWS pairing. The tradeoff: The upper treble is boosted and uneven, while the mids sit slightly behind the bass and highs, so it is not a neutral choice for vocal-focused music.
Why pick the JBL Charge 3: Doubles as a 6000mAh power bank for USB devices. ~20 hour battery life. The tradeoff: Less clarity than the Flip 4.
One note: the JBL Charge 3 is no longer in production and isn’t widely stocked new anymore.
Buy the Bogasing G4. It is rated higher for sound quality than the JBL Charge 3 and costs less, which makes it the one to get unless you need something the other one does better.

The Two Speakers In Full
Bogasing G4: $38.29 Amazon eBay
Pros: A 0.83kg travel-friendly speaker with 50W output, IPX7 protection, USB-C charging, aux and microSD playback, LC3 Bluetooth and TWS pairing. It reaches a useful 100dB maximum level and has a measured 56Hz -10dB bass point, giving it more low-end presence than many speakers of this size. Measured bass extension of 56Hz (-10dB).
Cons: The upper treble is boosted and uneven, while the mids sit slightly behind the bass and highs, so it is not a neutral choice for vocal-focused music. It has no app or user EQ, and its Super Bass and Vocal modes offer little practical differentiation according to listening tests.
