Short answer: the Monster Shock S22, though neither ranks well in its class. It ranks #136 of 175 medium speakers by sound quality, rated 2.6/5, at $39.99; the DOSS E-Go II ranks #145, rated 2.5/5, at $39.90. Close enough in price that the sound-quality gap is the deciding factor. 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.
The case for the DOSS E-Go II: Very portable (water bottle sized), truly waterproof (IPX6), 12-hour battery life, excellent value for money, fast Bluetooth pairing. Watch for: Horribly bad unless turned up, still not great.
The Monster Shock S22 is the longer-running pick. 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. It is rated for 17 hours of battery against 12 for the DOSS E-Go II. It charges over USB-C rather than Micro USB. Watch for: No measurements or substantive reviews, so its rating is estimated.
Buy the Monster Shock S22. It is rated higher for sound quality, and the $0.09 saving on the DOSS E-Go II is not enough to make up the difference.
About the ratings: the Monster Shock S22’s rating is estimated from measured siblings and predecessors rather than its own measurements, with a likely range of 2.2 to 3.0, so this verdict could change once it is measured.
