Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The JBL Boombox 4 ranks #17 of 70 boombox speakers by sound quality at $549.95; the Soundboks Mix ranks #28 of 46 party speakers by sound quality at $799.
What the JBL Boombox 4 gets right: Pretty insane output capability for its size. The catch: pretty overpriced for the category, and out of the box it sounds worse than the older Boombox 3 (an EQ preset helps).
On the Soundboks Mix side: IP65 dust/water resistance and 65W USB-C fast charging for its swappable battery. The tradeoff: only 72W from a single 10-inch woofer, well short of the Boombox 4’s output.
Buy the JBL Boombox 4 at $549.95 if you want a boombox speaker. Buy the Soundboks Mix at $799 if you want a party speaker instead.

The Two Speakers In Full
JBL Boombox 4: $549.95 Amazon Bhphotovideo
Pros: Pretty insane output capability for the size.
Cons: Pretty overpriced for the category. Better than the Boombox 3 mostly because there are more 7 EQ bands instead of just 3 and it can be better tuned. Try Oluv’s EQ for it. Out of the box sounds worse than the Boombox 3. No Aux input.

Soundboks Mix: $799 Soundboks Amazon
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.
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 4, and no microphone input for karaoke like the Pro Panel models.
