Short answer: the Soundcore Boom 3i. It ranks #31 of 175 medium speakers by sound quality, rated 4.0/5, at $118.99. The W-King D8 Mini ranks #135, rated 2.6/5, at $49.99, $69 cheaper, which does not close the gap in sound quality.
The Soundcore Boom 3i is the better-sounding, deeper-bass pick. Looks to be designed as a direct competitor to the JBL Charge 5 with a very similar sound profile, warm tuned with boosted bass. Its bass reaches about 56Hz before falling 10dB, against 63Hz for the W-King D8 Mini. At 1.7 lbs (783 g) it weighs much less than the W-King D8 Mini at 2.8 lbs (1.26 kg). It is rated IP68 against IPX6 for the W-King D8 Mini. Watch for: Not quite as good as a JBL Charge 5, doesn’t go quite as loud or sound quite as balanced, but very very close.
The W-King D8 Mini is the longer-running choice. 30W output with switchable indoor/outdoor EQ modes. It is rated for 24 hours of battery against 16 for the Soundcore Boom 3i. It keeps a wired aux input, which the Soundcore Boom 3i lacks. It plays in stereo from a single unit, unlike the Soundcore Boom 3i. Watch for: Recessed midrange, harsh treble.
Buy the Soundcore Boom 3i. It is rated higher for sound quality, and the $69 saving on the W-King D8 Mini is not enough to make up the difference.
