Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The Bogasing G4 ranks #25 of 142 medium speakers by sound quality at $38.59; the JBL Go 4 ranks #25 of 47 small speakers by sound quality at $49.95.
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 4 side: A little more bass than the Go 3 and they fixed the strange mids peak. The tradeoff: Not much bass at all, especially with electronic/bass-heavy tracks pushed past ~50% volume.
Buy the Bogasing G4 ($38.59) for a medium speaker; the JBL Go 4 ($49.95) suits a small speaker instead.
There is a real battery-life gap here: the Bogasing G4 is rated for 24 hours, the JBL Go 4 only 7 hours.

The Two Speakers In Full
Bogasing G4: $38.59 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.
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.

Pros: A little more bass than the Go 3 and they fixed the strange mids peak.
Cons: Not much bass at all, especially with electronic/bass-heavy tracks pushed past ~50% volume. Midrange can sound grainy and treble a bit sizzly; loses clarity at higher volumes.
