Short answer: the Ultimate Ears Hyperboom. It ranks #27 of 46 party speakers by sound quality at $450; the Soundboks Mix ranks #28 and costs $799, so there is not much of a tradeoff to weigh.
What the Soundboks Mix gets right: IP65 dust/water resistance and 65W USB-C fast charging for its swappable battery, plus TeamUp linking with up to 5 other SKAA speakers. The catch: only 72W from a single 10-inch woofer, and it can sound bright in the treble.
On the Ultimate Ears Hyperboom side: Dual Bluetooth pairing, aux and optical inputs, and up to 24 hours of battery at half volume, for $349 less. The tradeoff: our notes call it expensive for what it does - a bit dull and muddy, with bass not as deep as a Partybox 100.
Buy the Ultimate Ears Hyperboom. It ranks higher for sound quality than the Soundboks Mix and costs less, so there is no real case for the other one.
