Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The Sony ULT Tower 10 ranks #10 of 12 large party speakers by sound quality at $898.99; the Soundboks Mix ranks #25 of 40 party speakers by sound quality at $799.
Why pick the Sony ULT Tower 10: Louder than the Partybox Ultimate. The catch: Not as deep of bass and loses more bass at high volume even compared to the lower end Partybox speakers.
What the Soundboks Mix does well: 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. The catch: Doesn’t have as deep of bass as higher-ranked speakers, and can sound somewhat bright in the treble.
Buy the Sony ULT Tower 10 ($898.99) for a large party speaker; the Soundboks Mix ($799) suits a party speaker instead.
There is a real gap in water resistance: the Soundboks Mix at IP65 (water jets) against the Sony ULT Tower 10, which has no water resistance.

Soundboks Mix: $799 Soundboks Amazon eBay
Older model: the Soundboks Go (rated 3.1/5).
Pros: 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.
Cons: 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 Soundboks 4, and no microphone input for karaoke like the Pro Panel models.
