Short answer: the Hopestar A90. It ranks #22 of 91 boombox speakers by sound quality, rated 3.9/5, at $351.65; the Sony ULT Field 7 ranks #56, rated 3.2/5, and costs $400, so there is not much of a tradeoff to weigh.
The Hopestar A90 is the better-sounding pick. A huge, powerful 700W boombox with eight drivers (two 5” woofers, two 3.5” midranges and four tweeters), a removable 36,000mAh battery and a wireless microphone. Watch for: The JBL PartyBox Encore Essential 2 was the better, more refined listen in a direct comparison.
The Sony ULT Field 7 is the longer-running pick. It is rated for 30 hours of battery against 8 for the Hopestar A90. It has an adjustable EQ, which the Hopestar A90 lacks. The catch: A peak around 8kHz, and bass does not reach as deep as the top-ranked speakers.
Buy the Hopestar A90. It is rated higher for sound quality than the Sony ULT Field 7 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.

The Two Speakers In Full
Hopestar A90: $351.65 AliExpress eBay
Pros: A huge, powerful 700W boombox with eight drivers (two 5” woofers, two 3.5” midranges and four tweeters), a removable 36,000mAh battery and a wireless microphone. In side by side tests it had better highs, clarity and soundstage than the Zealot ZE21 while still reaching deep, reviewers picked it over the JBL Boombox 4 for its bass and output, and it sounded powerful and true to the music against the JBL PartyBox Encore Essential 2. Bluetooth 5.4 with Auracast, IPX6, USB, TF and aux inputs, RGB lights and a strap attachment.
Cons: The JBL PartyBox Encore Essential 2 was the better, more refined listen in a direct comparison. The Yeahbox Sonic Boom Ultra measured roughly 3 to 5dB louder. There is no app or EQ. It is very large and heavy (13.2 kg boxed), claims only 6 to 8 hours of battery, and it is sold through AliExpress rather than US retailers.
