Short answer: the Monster Shock S22, though neither ranks well in its class. Both are rated 2.6/5 for sound quality (#136 and #135 of 175 medium speakers), and the Monster Shock S22 costs $39.99 against $49.99 for the W-King D8 Mini, and with sound quality even, the cheaper one is the better buy. Both are rated below 3.0/5 among the 175 medium speakers, so if sound quality matters, consider the EarFun Uboom L instead, ranked #2 at $49.79.
Why pick the Monster Shock S22: Rated for 17 hours with IPX6 water resistance, Bluetooth 5.4, an aux input, TWS stereo pairing with a second unit and a built in carry handle, at a low price. The catch: No measurements or substantive reviews, so its rating is estimated.
The W-King D8 Mini is the longer-running pick. 30W output with switchable indoor/outdoor EQ modes. It is rated for 24 hours of battery against 17 for the Monster Shock S22. It has an adjustable EQ, which the Monster Shock S22 lacks. The tradeoff: Recessed midrange, harsh treble.
Buy the Monster Shock S22. Both are rated the same for sound quality, and it costs $10 less than the W-King D8 Mini.
Worth knowing: the Monster Shock S22 has not been measured yet. Its rating is estimated from related models, with a likely range of 2.2 to 3.0, so treat this verdict as provisional.
