Bring the party anywhere
Your backyard hangs, basement afters, and all-night ragers will never be the same. The JBL PartyBox 330 is here to bring the deep, punchy bass and crisp highs you crave while its wide soundstage and AI Sound Boost keep sound big, loud, and clear—even when you go full throttle on the volume.
But it’s not just about amazing sound. The JBL PartyBox 330 also sets the vibe. A futuristic lightshow moves to the beat, turning any room into a dance floor, while a refreshed top panel gives you fast access to audio and light effects.
Up to 18 hours of playtime means the music won’t quit before you do. A 10-minute charge adds another 2 hours, or swap in a spare battery (sold separately). Built with a telescopic handle with a secure locking mechanism, wide wheels that can handle grass or sand, and a splashproof design, taking this speaker on the road is effortless.
Plug in two mics and a guitar for an instant live set. 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. However you throw down, the JBL PartyBox 330 brings the main character energy.

Features and Benefits
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.
Up to 18 hours of playtime
One charge. All day energy. Up to 18 hours of playtime. And with Fast Charge, another 10 minutes of charging gives you two more hours
of music so you can always make it through last call. Still not enough? Swap in a backup battery (sold separately) and get right back into the groove.
Telescopic handle and wider, sturdy wheels
The JBL PartyBox 330 is made to move. Pop up the locking telescopic handle, tilt it back on the wide, sturdy wheels, and you’re off—cruising from the living room to the lawn or wherever the night decides to go.
Splash-proof
Sudden drizzle? No sweat. The IPX4 splash-proof design keeps the music going as long as y’all are out. Turn up the party with Auracast™
When the crowd gets bigger, your sound should too. Pair two PartyBox 330s for a wider stereo soundstage, or link a whole crew of JBL Auracast™-enabled speakers and let the music grow to match the moment.
Smart EQ mode
Smart EQ mode keeps your sound balanced based on what’s playing. It automatically adjusts the EQ in real time, recognizing whether
the content is primarily music or speech, so instruments stay full and punchy while voices come through clear, crisp, and easy to
understand. Whether you’re switching from music to a podcast or back again, everything sounds right without needing to touch a thing.
High-quality audio connections, from playlists to live sets
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 singalong setups. Then bring the live energy by plugging in microphones or a guitar—so anyone can jump in and be the star of the night.
Control from anywhere with JBL One app
You can control this speaker using the JBL One App from anywhere in the party, so you can change the song or adjust the lightshow from the dance floor.
Made with the planet in mind
The JBL PartyBox 330 incorporates post-consumer recycled plastic. It’s also packaged in FSC-certified paper printed with soy ink.

EasySing’s AI vocal removal can pull back the original lead vocals from your favorite songs, turning them instantly into karaoke tracks. Just plug-in and go—no extra setup, no fuss. It’s an easy way to give everyone a chance to shine without slowing the night down
