Short answer: the Zealot ZE51 on measured sound quality, the Havit BassBlast Go on price. The Zealot ZE51 ranks #16 of 89 boombox speakers, rated 4.1/5, at $296.39. The Havit BassBlast Go ranks #47, rated 3.4/5, at $77.99, $218.40 cheaper.
The case for the Zealot ZE51: Cleaner sound and a wider stereo soundstage than the Zealot ZE41, with less distortion at high volume for better instrumental detail and clarity. The catch: The Zealot ZE41 still wins on raw bass depth and price.
Why pick the Havit BassBlast Go: Jagist found it a strong value for a medium size boombox, with a lot of bass for its size and a good balance on the Rock EQ. The tradeoff: In the only side by side against a rated speaker, listeners preferred the W-King H330, and Techder Audios found the Tribit Stormbox Lava clearly better in sound and build.
Buy the Zealot ZE51 if sound quality is the priority over the price, or the Havit BassBlast Go if the price is the priority over sound quality.
Battery life favors the Havit BassBlast Go: rated for 12 hours against 4 hours for the Zealot ZE51.

Zealot ZE51: $296.39 after coupon Amazon AliExpress eBay
Pros: Cleaner sound and a wider stereo soundstage than the Zealot ZE41, with less distortion at high volume for better instrumental detail and clarity.
Cons: The Zealot ZE41 still wins on raw bass depth and price. Large and heavy like the rest of the boombox class, and clarity still isn’t up to dedicated hi-fi speakers.

Havit BassBlast Go: $77.99 Amazon eBay
Pros: Jagist found it a strong value for a medium size boombox, with a lot of bass for its size and a good balance on the Rock EQ. Two woofers and two tweeters give true stereo from one unit, and it adds IPX6 water resistance, Bluetooth 5.3, the Havit Life app with 8 EQ presets, a 6.35mm microphone input with echo control, aux and USB playback, a small status screen, RGB lights, stereo pairing and a power bank output.
Cons: In the only side by side against a rated speaker, listeners preferred the W-King H330, and Techder Audios found the Tribit Stormbox Lava clearly better in sound and build. Vocals are weaker than rivals’, and owners report the battery drains far faster than its 12 hour rating. The evidence is thin: one comparison and a handful of listening reviews.
