Short answer: the Tribit Stormbox Blast. It ranks #2 of 113 boombox speakers by sound quality, the Go + Play 3 ranks #3, and the Stormbox Blast costs $185.01 less, so there is not much of a tradeoff to weigh.
The Go + Play 3’s appeal is a specific sound signature, not overall polish. Our notes describe warm sound with boosted bass, but note it’s just a little over half as loud as the higher rated boomboxes in this class. It also carries no water resistance at all and runs only 8 hours on battery.
The Stormbox Blast punches well above its size class. Our notes call it an amazing speaker for its size that competes well with some speakers in the larger Party size class. Its shortcomings are minor by comparison: it lacks a bit of detail next to the top-ranked speakers in other size categories, and has a dip around 5.5kHz.
Battery life and water resistance both favor the Stormbox Blast heavily: a 30 hour rated battery against the Go + Play 3’s 8 hours, and an IPX7 rating for brief submersion against no rating at all on the Go + Play 3.
Everything else is close: both offer an app with EQ, stereo pairing, and TWS, though the Stormbox Blast’s 10-band EQ gives more granular control than the Go + Play 3’s app EQ, and it edges out the Go + Play 3 slightly on max volume at 108dB versus 103dB.
Buy the Tribit Stormbox Blast for equal or better sound quality, a much longer battery, real water resistance, and a lower price. It is the stronger choice on nearly every measure here.
