Short answer: the Monster Shock S22, though neither ranks well in its class. Both are rated 2.6/5 for sound quality (#136 and #137 of 175 medium speakers), and the Monster Shock S22 costs $39.99 against $49.99 for the Monster S380, so with nothing between them on sound quality, price settles it. Both are rated below 3.0/5 among the 175 medium speakers, and the EarFun Uboom L, ranked #2 at $49.79, is a better place to start if sound quality matters.
Why pick the Monster S380: Rated for 20 hours with IPX6 water resistance, Bluetooth 6.0, aux and microSD inputs, a speakerphone microphone, TWS stereo pairing and a carry lanyard for about $50. Watch for: No measurements or substantive reviews, so its rating is estimated, and the 40 watt claim is unverified.
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.
Buy the Monster Shock S22. Both are rated the same for sound quality, and it costs $10 less than the Monster S380.
About the ratings: neither speaker has been measured yet, so both ratings are estimated from measured siblings and predecessors (likely ranges: Monster S380 2.2 to 3.0; Monster Shock S22 2.2 to 3.0). Treat this verdict as provisional.
