Take the party anywhere
Your backyard get-togethers, house parties, and all-night drives will never be the same. The JBL PartyBox 330 delivers the deep, punchy bass and crisp highs you crave, while the wide soundstage and AI Sound Boost technology keep the sound powerful, loud, and clear—even when you crank the volume to the max.
But it’s not just about great sound. The JBL PartyBox 330 also sets the mood. The futuristic light show moves to the beat of the music and transforms any space into a dance floor, while the updated top panel provides quick access to sound and lighting controls.
Up to 18 hours of playback means the music won’t end before you do. A quick 10-minute charge adds another 2 hours, or you can swap out the battery (sold separately). Thanks to the telescoping handle with a locking mechanism, wide wheels suitable for grass or sand, and splash resistance, transporting the speaker is a breeze.
Plug in two microphones and a guitar to create an instant live set. The Auracast™ feature lets you connect to other Auracast-enabled JBL speakers and amplify the sound. And you can control everything from anywhere using the JBL One app. No matter what kind of event you’re hosting, the JBL PartyBox 330 will provide the main energy.

Features and Benefits
Bring the energy with legendary JBL sound
Turn up the volume and experience what 280 watts of legendary JBL sound feels like. Two 6.5" woofers deliver deep bass you can feel in your chest, while two 25 mm PEN-diaphragm tweeters maintain crisp melodies and clear harmonies. Plus, the wider soundstage draws everyone into the action. The whole crowd will feel it—not just the front row.
AI Sound Boost makes everything sound even more powerful
AI Sound Boost analyzes your music in real time and predicts driver movement to maximize bass and volume while minimizing distortion. The result is a bigger, clearer sound that retains its dynamics even at maximum volume.
Adaptive Futuristic Light Show
A futuristic light show that truly dances with you. Smooth, undulating light effects and bold strobes sync with the beat of the music, and with a variety of patterns, you can customize the lights to match whatever mood the night brings.
Up to 18 hours of playback
One charge. Power for the whole day. Up to 18 hours of playback. And thanks to the fast-charge feature, 10 minutes of charging gives you another two hours of music, so you’ll always make it to the end. Still not enough? Swap in a spare battery (sold separately) and get right back in the groove.
Telescoping handle and wider, durable wheels
The JBL PartyBox 330 is built to move. Extend the telescoping handle with its locking mechanism, tilt it onto the wide, sturdy wheels, and head out—from the living room to the backyard or wherever the night takes you.
Splash-resistant
A sudden downpour? No problem. IPX4-certified splash resistance keeps the music going as long as you’re outdoors.
Take your party to the next level with Auracast™
When the crowd grows, so should the sound. Pair two PartyBox 330 speakers for a wider stereo soundstage, or connect an entire set of Auracast™-enabled JBL speakers and let the music grow with the moment.
Smart EQ Mode
Smart EQ Mode maintains a balanced sound based on what’s playing. It automatically adjusts the equalizer in real time and recognizes whether the content is primarily music or speech, so instruments sound full and rich, while voices are clear, crisp, and easy to understand. Whether you’re switching from music to a podcast or back again, everything sounds just right without having to adjust anything.
High-quality audio connectivity, from playlists to live performances
Use the USB-C input for lossless audio from your favorite streaming or karaoke apps, or connect your TV via the optical input for easy karaoke nights. Then add some live energy by plugging in microphones or a guitar so anyone can join in and become the star of the night.
Control it from anywhere with the JBL One app
You can control this speaker using the JBL One app from anywhere at the party, so you can change songs or adjust the light show right from the dance floor.
Made with the planet in mind
The JBL PartyBox 330 speaker contains recycled plastic from post-consumer waste. It’s also packaged in FSC-certified paper printed with soy-based ink.
Compatible with JBL EasySing microphones
The JBL PartyBox 330 works seamlessly with JBL EasySing microphones, so karaoke moments are always ready to go. EasySing’s AI vocal removal feature can suppress the original lead vocals in your favorite songs and instantly turn them into karaoke versions. Just plug it in and play—no complicated setup, no delays. It’s an easy way to give everyone a chance to shine without slowing down the evening’s festivities.
