Short answer: the Tribit Stormbox Blast. It ranks #2 of 75 boombox speakers by sound quality, the Go + Play 3 ranks #3, and the Stormbox Blast costs $205.01 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.

The Two Speakers In Full
Harman Kardon Go + Play 3: $385 Amazon eBay
Pros: Warm sound with boosted bass. Deepest bass out of any speaker in this size. Sound is more natural than the Go + Play2. Measured bass extension of 35Hz (-10dB).
Cons: Just a little over half as loud as the higher rated boomboxes. Only 8 hours of battery at medium volume. No water rating.
Setup: Use the hidden EQ modes to adjust the bass up when outside and down when inside. To adjust bass, quickly press the bluetooth and volume down buttons together, the number of light flashes tell you what mode you’re in. To adjust treble, quickly press the volume up and phone buttons at the same time, the number of yellow flashes on the light tell you what mode you are in.

Tribit Stormbox Blast: $179.99 Amazon eBay
Pros: Amazing speaker given its size, competes well with some speakers in the Party size class, bass almost as deep as a Partybox 100. Quite neutral in the default and xbass modes, but try Oluv’s EQ or Alan Ross’s EQ for a slightly more neutral sound. Oluv has mentioned v3.5 now uses his EQ as the defaults and sounds extremely good. 2 different light modes or can be turned off. Measured bass extension of 43Hz (-10dB).
Cons: Lacks a bit of detail compared to the top ranked speakers in other size categories, dip at 5.5kHz. Without the above EQ this speaker would rank around #4 in the rankings. The curved underside of the handle makes it a little harder to grip and can be uncomfortable to carry long distances.
