Features and technical details

JBL PartyBox 330

The JBL PartyBox 330 shows up loud and clear.

Unreal sound quality meets a wider soundstage and AI Sound Boost to power bold bass and crystal-clear highs—all while a beat-synced lightshow boosts the vibe.

With up to 18 hours of playtime, splash-proof design, telescopic handle, and all-road wheels, this speaker moves with the party wherever it goes.

A 10-minute charge adds another 2 hours, or swap in a spare battery (sold separately).

Want even bigger sound?

Auracast™ lets you pair with other Auracast-enabled JBL speakers to double or triple the sound power.

And you can control it all from anywhere with the JBL One App.

Bring the energy with JBL legendary sound

Crank it up and experience what 280 watts of legendary JBL sound feels like.

Dual 6.5" woofers bring deep, chest-hitting bass, while twin 25mm PEN dome tweeters keep hooks sharp and harmonies clear.

All while a wider soundstage pulls everyone into the mix.

The whole crowd will feel it—not just the front row.

AI Sound Boost makes everything hit harder

AI Sound Boost reads your music in real time and predicts driver movement to max out your bass and volume while minimizing distortion.

Translation: bigger, cleaner sound that stays punchy even when you crank the music all the way up.

Adaptive futuristic lightshow

A futuristic lightshow that actually dances with you.

Sweeping ripple light trails and punchy strobes all sync to the beat—and with a variety of patterns to play with, you can match the lights to every mood the night throws at you.

JBL PartyBox 330: Big sound.

Built to move

The JBL PartyBox 330 delivers 280W of total output power.

Feel deep, chest-thumping bass that brings every track to life, powered by dual 6.5″ woofers.

Making its PartyBox debut, twin PEN dome tweeters bring the same pro-grade technology used in JBL systems that power concerts for thousands, delivering crisp, clear highs that cut through the mix.

The new shape, ripple-effect side panel – built from miniature JBL horns – and a reinvented lightshow with beat-synced dynamics are a visual expression of all of that pure power.

Up to 18 hours of playtime and Fast Charge keep the music going as long as the party does, and an easily replaceable battery* means the party never has to stop.

A telescopic locking handle and all-terrain wide wheels make it effortless to move.

Capture the live energy with dual mic and guitar inputs, perfect for sing-alongs and jam sessions.

The new optical TV input makes it easy to connect the PartyBox 330, while USB-C delivers lossless audio.

With Auracast™, users can pair multiple JBL speakers to scale the sound as the crowd grows.
