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.
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.
