Short answer: the Yeahbox Sonic Boom Ultra. It ranks #11 of 91 boombox speakers by sound quality, rated 4.2/5, at $388. The Tronsmart Halo 200 ranks #67, rated 2.8/5, at $169.99, $218.01 cheaper, not enough of a saving to outweigh the sound-quality gap.
The Yeahbox Sonic Boom Ultra is the better-sounding, longer-running option. By far the loudest boombox tested against it, hitting 106-107dB, roughly 3-5dB louder than the JBL Boombox 4, Zealot ZE41, Tribit Stormbox Blast 2, W-King X20, and Hopestar A90/A95. It is rated for 24 hours of battery against 18 for the Tronsmart Halo 200. It is rated IPX6 against IPX4 for the Tronsmart Halo 200. The tradeoff: The 500W peak-power rating doesn’t fully hold up: it gets noisy above roughly 80-90% volume, and the midrange isn’t fully refined, sometimes sitting a touch too forward.
The Tronsmart Halo 200 is the lighter option. 15,000mAh battery rated 18 hours; charges in 3.5 hours. At 13.4 lbs (6.1 kg) it weighs much less than the Yeahbox Sonic Boom Ultra at 24.3 lbs (11 kg). The tradeoff: Not as deep bass as some of the top ranked.
Buy the Yeahbox Sonic Boom Ultra. It is rated higher for sound quality, and saving $218.01 with the Tronsmart Halo 200 does not make up for the sound-quality gap.

The Two Speakers In Full
Yeahbox Sonic Boom Ultra: $388.00 Amazon eBay
Pros: By far the loudest boombox tested against it, hitting 106-107dB, roughly 3-5dB louder than the JBL Boombox 4, Zealot ZE41, Tribit Stormbox Blast 2, W-King X20, and Hopestar A90/A95. The massive 6x9in racetrack woofer reaches audible bass down to around 30Hz on the Country EQ preset, and a teardown confirmed genuinely robust internals: a thick vented voice coil and a dedicated crossover output per driver. HDMI ARC input/output lets it double as a TV soundbar, a feature none of its direct competitors offer.
Cons: The 500W peak-power rating doesn’t fully hold up: it gets noisy above roughly 80-90% volume, and the midrange isn’t fully refined, sometimes sitting a touch too forward. The custom EQ in the app noticeably reduces bass output compared to the factory presets and doesn’t persist after the speaker powers off. No Auracast, no removable battery, a plastic handle with some flex, and heavy at 11kg (24lb) for $388. Most of the sound-quality coverage comes from enthusiast listening-test comparisons rather than independent measurement.
