These are not really the same size class, and that is the honest framing here. The Bogasing G4 ranks #25 of 142 medium speakers by sound quality at $38.29; the JBL Go 3 ranks #26 of 47 small speakers by sound quality at $39.95.
What the Bogasing G4 gets right: Clear sound with punchy bass, exceptional 24-hour battery life, IPX7 waterproof, multiple sound modes for different music styles. The tradeoff: Some boosted treble that’s wavy up top.
On the JBL Go 3 side: Genuinely pocket-sized at 209g. Set against that: Not much bass at all, strange mids peak.
Buy the Bogasing G4 at $38.29 if you want a medium speaker. Buy the JBL Go 3 at $39.95 if you want a small speaker instead.
Battery life favors the Bogasing G4: rated for 24 hours against 5 hours for the JBL Go 3.

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.
