JBL PartyBox 330 Portable Party Speaker 280W

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 sing-along 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.

Compatible with JBL EasySing Mics

The PartyBox 330 works seamlessly with JBL EasySing Mics, so karaoke moments are always on deck. 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.
