Short answer: the Zealot ZE21. It ranks #18 of 89 boombox speakers by sound quality, rated 4.0/5, at $247.41. The Tronsmart Halo 200 ranks #65, rated 2.8/5, at $169.99, $77.42 cheaper, not enough of a saving to outweigh the sound-quality gap.
What the Zealot ZE21 does well: The ZE21’s main attraction is unusually deep bass for a battery boombox: owner testing finds real output in the 40-50Hz region and audibility down toward the low 30s. The tradeoff: That deep-bass emphasis comes with a pronounced 60-110Hz kick-bass dip and over-loud 250-600Hz lower mids, which can make rock and pop sound hollow or boxy.
Why pick the Tronsmart Halo 200: 15,000mAh battery rated 18 hours; charges in 3.5 hours. The tradeoff: Not as deep bass as some of the top ranked.
Buy the Zealot ZE21. It is rated higher for sound quality, and the $77.42 saving on the Tronsmart Halo 200 is not enough to make up the difference.

The Two Speakers In Full
Zealot ZE21: $187.15 Amazon AliExpress eBay
Pros: The ZE21’s main attraction is unusually deep bass for a battery boombox: owner testing finds real output in the 40-50Hz region and audibility down toward the low 30s. Its TWS button can form a stereo pair with another compatible Zealot, and its large, rugged chassis gives it credible party-speaker scale. Measured bass extension of 36Hz (-10dB).
Cons: That deep-bass emphasis comes with a pronounced 60-110Hz kick-bass dip and over-loud 250-600Hz lower mids, which can make rock and pop sound hollow or boxy. The supplied sound modes do not fully correct the tuning; the most positive independent report required source-side parametric EQ. Treble is also soft and clarity trails better-tuned rivals.
