Last updated: September 26, 2026

Short answer: the JBL Boombox 4. It ranks #20 of 85 boombox speakers by sound quality, rated 4.0/5, at $429.95. The Hopestar A90 ranks #22, rated 3.9/5, at $351.65, $78.30 cheaper, not enough of a saving to outweigh the sound-quality gap.

JBL Boombox 4 vs Hopestar A90

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 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 $78.30 saving on the Hopestar A90 is not enough to make up the difference.

Older models: the JBL Boombox 3 (ranked lower, rated 3.8/5), the JBL Boombox 2 (ranked lower, rated 3.5/5) and the JBL Boombox (ranked lower, rated 2.9/5).

Pros: Pretty insane output capability for the size. IP68 protection and Auracast pairing with other current JBL speakers. Measured bass extension of 41Hz (-10dB).

Cons: Pretty overpriced for the category. Better than the Boombox 3 mostly because there are more 7 EQ bands instead of just 3 and it can be better tuned. Try Oluv’s EQ for it. Out of the box sounds worse than the Boombox 3. No Aux input.

Hopestar A90: $351.65 AliExpress eBay

Hopestar A90 ranking card

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, and the evidence is listening comparisons rather than measurements. 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.
