These are not really the same size class, and that is the honest framing here. The JBL Partybox 130 ranks #7 of 40 party speakers by sound quality at $449.95; the Yeahbox Sonic Boom Ultra ranks #11 of 76 boombox speakers by sound quality at $388.
Different sizes. The PartyBox 130 is an 11.3 kg party speaker with a foldable handle. The Sonic Boom Ultra is an 11 kg boombox. Each is rated within its own class, and they weigh almost the same.
The PartyBox 130 is balanced and powerful for its format, with a removable battery, a claimed 15 hours, mic and guitar inputs, USB audio, Auracast and a light show. It is bass forward and less clear than the PartyBox 120 in direct comparisons.
The Sonic Boom Ultra was the loudest boombox in comparison tests, reaches audible bass near 30Hz on its Country preset, and has HDMI ARC for TV use and a claimed 24 hours. It gets noisy above about 80 to 90% volume and has no Auracast or removable battery.
Weather: IPX6 on the Yeahbox against IPX4 on the PartyBox 130.
Buy the JBL Partybox 130 at $449.95 for a party speaker, or the Yeahbox Sonic Boom Ultra at $388 for a boombox speaker instead.

The Two Speakers In Full
JBL Partybox 130: $449.95 Amazon eBay
Pros: A relatively manageable 11.3kg PartyBox with removable battery, foldable handle, light show, USB audio and modern JBL connectivity. Independent reviews describe it as unusually balanced and powerful for its format, while owner feedback praises clear voices and deep bass.
Cons: It is still bass-forward and less clear than the PartyBox 120 in direct comparisons. The smaller battery and stripped-back controls/features make it a questionable upgrade when the 120 is similarly priced. JBL’s wired daisy chain only works with other JBL speakers.

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.
