The JBL PartyBox 330 delivers powerful sound with a wider soundstage and AI Sound Boost for bold bass and crystal-clear highs, all complemented by a beat-synced lightshow that elevates the party atmosphere. With up to 18 hours of playtime, a splashproof design, a telescopic handle, and sturdy all-terrain wheels, this speaker moves with the party wherever it goes. A 10-minute charge adds another two hours of playback, or a spare battery (sold separately) can be swapped in to keep the music going. For an even bigger sound experience, Auracast™ allows connections with other Auracast™-enabled JBL speakers to expand the sound. The JBL One app provides convenient control from anywhere at the party.

Features

BRING THE ENERGY WITH JBL LEGENDARY SOUND

Turn up the volume and experience 280 watts of legendary JBL sound. Dual 6.5-inch woofers deliver deep, powerful bass, while twin 25mm PEN dome tweeters keep hooks sharp and harmonies clear. A wider soundstage draws the entire crowd into the music, so everyone can feel the energy-not just the front row.

AI SOUND BOOST MAKES EVERYTHING HIT HARDER

AI Sound Boost analyzes music in real time and predicts driver movement to maximize bass and volume while minimizing distortion. The result is bigger, cleaner sound that stays punchy even at high volumes.

ADAPTIVE FUTURISTIC LIGHTSHOW

A futuristic lightshow dances along with the music. Sweeping ripple light trails and striking strobe effects sync to the beat. With a variety of patterns to choose from, the lighting can match every mood throughout the night.

UP TO 18 HOURS OF PLAYTIME

Enjoy all-day energy with up to 18 hours of playtime on a single charge. Fast Charge provides another two hours of music with just 10 minutes of charging, helping the party continue well into the night. If even more playback time is needed, simply swap in a backup battery (sold separately) and get straight back to the music.

SPLASHPROOF DESIGN

Unexpected drizzle is no problem. The IPX4 splashproof design helps protect the JBL PartyBox 330 from splashes, keeping the music going during outdoor gatherings.

SMART EQ MODE

Smart EQ Mode automatically adjusts the equalizer in real time based on the audio content, recognizing whether the primary focus is music or speech. Instruments remain full and punchy, while voices sound clear, crisp, and easy to understand. Whether switching from music to a podcast or back again, the sound stays balanced without requiring manual adjustments.

CONTROL FROM ANYWHERE WITH THE JBL ONE APP

Control the JBL PartyBox 330 from anywhere at the party using the JBL One app. Change tracks, adjust settings, and customize the lightshow without needing to stand beside the speaker.

COMPATIBLE WITH JBL EASYSING MICS

The PartyBox 330 works with JBL EasySing Mics, making karaoke easy to enjoy at any gathering. EasySing's AI vocal removal technology reduces original lead vocals from favorite songs, turning them into karaoke tracks. Simply connect the microphone and start singing-no complicated setup required. It's an easy way to let everyone enjoy the spotlight without interrupting the party.

TELESCOPIC HANDLE AND WIDE, STURDY WHEELS

The JBL PartyBox 330 is designed for easy portability. Extend the locking telescopic handle, tilt the speaker back onto its wide, sturdy wheels, and roll it smoothly from the living room to the lawn or wherever the party leads.

TURN UP THE PARTY WITH AURACAST™

As the crowd grows, expand the sound to match. Pair two PartyBox 330 speakers for a wider stereo soundstage, or connect multiple JBL Auracast™-enabled speakers to create a powerful sound experience for larger gatherings.

HIGH-QUALITY AUDIO CONNECTIONS, FROM PLAYLISTS TO LIVE SETS

Use the USB-C input for lossless audio from compatible streaming or karaoke apps, or connect a TV through the optical input for convenient sing-along sessions. Microphone and guitar inputs make it easy to add live performances, giving everyone a chance to join in and take the spotlight.

MADE WITH THE PLANET IN MIND

The JBL PartyBox 330 incorporates post-consumer recycled plastic. Its packaging also uses FSC-certified paper printed with soy ink.
