Short answer: the Stage 320, and save $80. These rank #1 and #2 out of 44 party speakers, and the gap between them is much smaller than the price and the spec sheet imply.
The power difference does not translate into a sound difference. The 330 has 280 W against the Stage 320’s 240 W. Our notes on the 330 are explicit that its sound quality is nearly identical to the Stage 320 and the older 310 despite the bump. If you already own either of those, the 330 is not an upgrade worth paying for.
What the 330 genuinely adds:
- An optical TV input and USB-C lossless playback, which the Stage 320 lacks. If you want the speaker to double as a TV system, this is the one real reason to choose it.
- Dual microphone and guitar inputs for karaoke and live sets.
- A different, more customizable light show — some people prefer the older design.
What the 330 removes: the dedicated microphone gain and control knobs found on the 310 and 320. If you run karaoke regularly, that is a downgrade in usability even though the input count went up.
Everything else matches: 18 hours of battery, a removable battery on both, IPX4, wheels and a telescoping handle, Auracast, and within 600 g of each other in weight.
Buy the Stage 320 unless you specifically need the optical input or the second microphone channel. It is the same performance for less money.
Buy the 330 if the TV input matters, or if you want the extra mic and guitar channels and can live without the dedicated gain knobs.

The Two Speakers In Full
JBL Partybox 330: $629.95 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.
