Short answer: the Bogasing G4. It ranks #27 of 175 medium speakers by sound quality, rated 4.0/5, at $38.29; the W-King D8 Mini ranks #135, rated 2.6/5, and costs $49.99, so there is little reason to consider the other one.
The Bogasing G4 is the better-sounding, deeper-bass option. A 1.8 lbs (0.83 kg) travel-friendly speaker with 50W output, IPX7 protection, USB-C charging, aux and microSD playback, LC3 Bluetooth and TWS pairing. Its bass reaches about 56Hz before falling 10dB, against 63Hz for the W-King D8 Mini. At 1.8 lbs (830 g) it weighs noticeably less than the W-King D8 Mini at 2.8 lbs (1.26 kg). 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.
What the W-King D8 Mini does well: 30W output with switchable indoor/outdoor EQ modes. It has an adjustable EQ, which the Bogasing G4 lacks. The catch: Recessed midrange, harsh treble.
Buy the Bogasing G4. It is rated higher for sound quality than the W-King D8 Mini and costs less, so it is the default pick unless a specific strength of the other one matters more to you.

The Two Speakers In Full
Bogasing G4: $38.29 Amazon $38.29 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.
