Short answer: the Bogasing M5. It ranks #61 of 177 medium speakers by sound quality, rated 3.5/5, at $52.99; the W-King D8 Mini ranks #135, rated 2.6/5, at $49.99. The price gap is small enough that the sound-quality ranking should decide it.
The Bogasing M5 is the better-sounding, lighter pick. A compact, backpack friendly speaker with very long battery life and USB-C charging at a budget price. At 1.7 lbs (757 g) it weighs much less than the W-King D8 Mini at 2.8 lbs (1.26 kg). The catch: Front/rear driver configuration.
The W-King D8 Mini is the louder pick. An inexpensive water resistant stereo speaker with indoor and outdoor sound modes and a long rated battery. Alan Ross Reviews measured it at 100dB at full volume, against 96dB for the Bogasing M5. It plays in stereo from a single unit, unlike the Bogasing M5. Watch for: Recessed midrange, harsh treble.
Buy the Bogasing M5. It is rated higher for sound quality, and saving $3 with the W-King D8 Mini does not make up for the sound-quality gap.
