Short answer: the Zealot PT21. It ranks #12 of 39 party speakers by sound quality at $225.86; the Soundboks Mix ranks #24 and costs $799, so there is little reason to consider the other one.
What the Soundboks Mix offers: USB-C fast charging (65W) for the swappable battery, up to 40 hours of battery life at mid-volume, IP65 dust/water resistance, and TeamUp linking with up to 5 other SKAA-equipped Soundboks speakers. High efficiency drivers reach 2-3x the volume of typical speakers for the same wattage. Watch for: Doesn’t have as deep of bass as higher-ranked speakers, and can sound somewhat bright in the treble. Only 72W of output and a single 10-inch woofer, less powerful than the Soundboks Go or 4, and no microphone input for karaoke like the Pro Panel models.
What the Zealot PT21 offers: 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. Watch for: 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.
Buy the Zealot PT21. It ranks higher for sound quality than the Soundboks Mix and costs less, so there is no real case for the other one.
