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.

JBL Partybox Stage 320: $549.95 Amazon Bhphotovideo Ebay refurbished
Pros: Handle and wheels are convenient. Customizable color lighting modes. Keeps more bass than the 310 at high volume. Removable battery.
Cons: Slightly sibilant in the treble at full blast. Very large. Note, JBL daisychain is not compatible with any other non-JBL speaker and is possibly a fully digital signal.
