About this product

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 splash-proof 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

  • 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* 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.

    Great speaker

    The sound quality is outstanding, with deep, powerful bass and crystal-clear highs, even at high volume. The battery lasts a long time, the light show adds a fun atmosphere, and it’s easy to move around thanks to the built-in wheels and handle. Whether it’s for backyard parties, family gatherings, or just enjoying music at home, this speaker delivers every time. Definitely worth the investment. I highly recommend it to anyone looking for loud, high-quality sound in a portable package.

    Beast of a speaker

    I’ve never written a review before, but this speaker is absolutely top notch. Bass is excellent (maybe slightly too much imo, but not a bad thing at all bc most speakers usually have too little bass for me). The vocals and music are clear. The light show is epic and underrated bc it changes depending on what you’re listening to. It was easy to transport to a friend’s house for a weekend party. Even up and down stairs was a cinch bc it’s somehow not that heavy. A really great product. 10 outta 10!
