Short answer: the Bogasing G4. It ranks #25 of 142 medium speakers by sound quality at $38.29; the W-King D8 Mini ranks #109 and costs $38.93, so there is little reason to consider the other one.
What the Bogasing G4 offers: 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. Watch for: 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.
What the W-King D8 Mini offers: 30W output with switchable indoor/outdoor EQ modes. IPX6 rated with a 5000mAh battery. Watch for: Recessed midrange, harsh treble. Bass doesn’t go as deep as others.
Buy the Bogasing G4. It ranks higher for sound quality than the W-King D8 Mini and costs less, so there is no real case for the other one.
Skip the W-King D8 Mini if sound quality matters to you. It ranks near the bottom of the 142 medium speakers.
