The Two Speakers In Full
JBL Partybox 330: $579.95 Amazon Bhphotovideo
Pros: Handle and wheels are convenient. Customizable lightshow. Removable battery. Slightly more power than the 310 and Stage 320 (280W vs 240W). Adds an optical TV input and USB-C lossless playback, plus dual mic and guitar inputs for karaoke and live sets.
Cons: Sound quality is nearly identical to the 310 and Stage 320 despite the power bump, so probably not worth an upgrade if you already own either of those. Removed the dedicated mic gain and microphone control knobs found on the 310/320. Some people don’t like the new lightshow design. Very large. Note, JBL daisychain is not compatible with any other non-JBL speaker and is possibly a fully digital signal.
