#12 Zealot PT21: $216.73 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.

How it compares: Just above it: Onn XL Wireless Party Speaker - $23 more, 44 fewer hours of battery life. Just below it: Sony SRS-XP700 - $166 more, 35 fewer hours of battery life.
