Short answer: the JBL Boombox 4. It ranks #20 of 113 boombox speakers by sound quality, rated 4.0/5, at $549.95. The Hopestar A90 ranks #22, rated 3.9/5, at $351.65, $198.30 cheaper, not enough of a saving to outweigh the sound-quality gap.
Side by side, the reviewer took the Hopestar for its deeper, bigger bass and output, calling it half the price with features the JBL lacks. The Boombox 4 is far smaller and lighter, which makes it the one to carry.
The Boombox 4 is measured at about 115dB with bass to about 41Hz, and it is IP68 with a removable battery and a claimed 28 hours. Use the Oluv EQ linked on its page.
The A90 is huge at 29.1 lbs (13.2 kg) boxed, with a removable battery, a wireless mic, Auracast and IPX6, but only 6 to 8 hours claimed. The A90’s rating comes from listening comparisons, not measurements, and it is sold through AliExpress rather than US retailers.
Buy the JBL Boombox 4. It is rated higher for sound quality, and the $198.30 saving on the Hopestar A90 is not enough to make up the difference.
