Short answer: the Bogasing G4. It ranks #27 of 177 medium speakers by sound quality, rated 4.0/5, at $42.49; 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 light, affordable waterproof speaker with surprisingly strong bass for its size, solid loudness, long battery life and stereo 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: An inexpensive water resistant stereo speaker with indoor and outdoor sound modes and a long rated battery. 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.
