Short answer: the Stage 320, and save $50. These rank #2 and #3 out of 39 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: $549.95 Amazon B&H Photo Video eBay
Pros: A highly complete rolling party speaker: removable battery, telescoping handle and wheels, light show, Auracast, USB-C lossless and optical inputs, plus dual mic/guitar inputs. It supplies a little more power than the JBL Partybox 310 and JBL Partybox Stage 320, while reviewers report better midrange clarity than the older JBL Partybox 310 and the same deep party-speaker bass.
Cons: It remains very large and heavy, and the sound improvement over the JBL Partybox Stage 320 is modest rather than transformational. JBL removed the dedicated mic gain/control knobs found on earlier models, a real drawback for frequent karaoke use. Do not upgrade from a JBL Partybox 310 or JBL Partybox Stage 320 just for the higher watt figure.
