JBL PartyBox 330 Portable Bluetooth Party Speaker (Hong Kong Licensed)
The PartyBox 330 is JBL's 2026 entry in the 300 series and takes the Stage 320's slot directly. Same chassis, same pair of 6.5-inch woofers, but four things the 320 does not have: 280W (the 320 is 240W), Bluetooth 6.0 with Auracast multi-speaker sync, AI Sound Boost, and a redesigned light show. Eighteen hours on a charge, ten minutes of fast charging for two hours of play, and a battery you can swap.
Seventeen kilograms, on wheels with a telescopic handle, and it rolls across grass and sand. This is a throw-a-party speaker, not a bedside one.

Put simply: if the 320 is still in stock and cheaper, and you don't mind last-generation Bluetooth or need several speakers in sync, the 320 saves money. If you want Auracast to link several units at once — or plan to add more later — go straight to the 330. The Stage 320 is here.
Auracast: several speakers, no pairing one by one
Bluetooth 6.0 with Auracast is the most useful upgrade in this generation. One 330 acts as the host; any other Auracast-capable JBL speaker — including a second 330 — joins with a tap, no individual pairing. Put one at each end of a rooftop and the sound stays in sync with no delay.
Karaoke and jam sessions
Two 6.35 mm inputs take two microphones at once, or a mic and a guitar. No microphone is included — for karaoke, add JBL's EasySing wireless mic or a wireless system from the microphone collection. The JBL One App adjusts mic echo and reverb.
Power: 18 hours, and 10 minutes buys 2 hours
A 68 Wh battery rated for up to 18 hours (moderate volume, lights off). Loud with the light show on will be much shorter — for an all-nighter, keep it plugged in. Ten minutes of fast charging gives roughly two hours, enough to top up before heading out. The battery pack is removable, so a spare means swapping instead of waiting three hours.
It rolls, but it is not small
Seventeen kilograms. Wide wheels and a locking telescopic handle move it across floors, grass and sand; stairs mean carrying. IPX4 splash-proof — light rain and poolside are fine; do not treat it as waterproof.
Warranty and delivery
Hong Kong licensed stock, covered by JBL Hong Kong's manufacturer warranty — the term is as stated on the warranty card in the box. Details in the FAQ.
Non-TV items: SF Express cash-on-delivery, Lalamove/GogoX on request, or free pickup at the Kwun Tong showroom. At 17 kg on wheels, pickup or Lalamove is the practical route.
Frequently asked questions
Is the 330 worth the step up from the Stage 320?
It depends on Auracast. For a single speaker, the 320 and 330 are in the same sound bracket; with two or more speakers together, the 330's Auracast is where the difference lives.
Does it come with a microphone?
No. For karaoke, add a JBL EasySing or any wired 6.35 mm mic.
Can it run on mains power?
Yes — plugged in, it plays indefinitely. The battery is a backup, not the only power source.
How much is a replacement battery?
The JBL Battery 400 is sold separately and the price moves; WhatsApp us before ordering.
Can I hear it first?
The Kwun Tong showroom holds stock for viewing by appointment. It is a stockroom, not a demo room.
