Short answer: the Bogasing G4. It ranks #25 of 144 medium speakers by sound quality, rated 4.0/5, at $38.29. The Doss Soundbox Pro ranks #137, rated 2.1/5, at $29.99, $8.30 cheaper, which does not close the gap in sound quality.
What the Bogasing G4 does well: 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.
The case for the Doss Soundbox Pro: 20W output, waterproof (IPX6), excellent battery life (20 hours), extra bass button and LED lights, MicroSD card support, dual woofer drivers. The catch: Barely any bass.
Buy the Bogasing G4. It is rated higher for sound quality, and the $8.30 saving on the Doss Soundbox Pro is not enough to make up the difference.

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.
