Newer model: the JBL Partybox 330, ranked higher, rated 4.6/5.

Pros: Among the best-sounding party speakers in its size class, and it keeps more bass than the JBL Partybox 310 at high volume. Two 6.5-inch woofers and two tweeters run on 240W, with a removable battery rated for 18 hours, a 5-band app EQ, mic and guitar inputs and Auracast linking. A handle and wheels make the 16.5 kg cabinet easy to move, and the color lighting modes are customizable.

Cons: Slightly sibilant in the treble at full blast. Very large.

Zealot PT21: $225.86 AliExpress eBay

Pros: Dual 166mm woofers and 200W output in a lighter, more compact body than the ZE41, with a bundled wireless microphone and echo effect built in for karaoke. Quite deep bass for the price, even deeper than the JBL Boombox 4 in direct comparisons.

Cons: Unlike some other Zealot models, app-based EQ customization doesn’t appear to be fully supported yet, and IPX5 means it can handle splashes but not submersion.
