JBL PartyBox 330 Speaker (Black)

Crank it up and experience what 280W of legendary JBL Pro sound feels like. Dual 6.5" woofers deliver deep, powerful bass, while twin 25mm PEN dome tweeters keep highs crisp and harmonies clear. A wider soundstage pulls everyone into the heart of the music – the whole crowd will enjoy it, not just those in the front row.

AI Sound Boost makes everything even more powerful

AI Sound Boost technology analyzes your music in real time and predicts driver movement to boost bass and volume while reducing distortion. The result is bigger, cleaner, more powerful sound that stays punchy even at maximum volume.

Adaptive futuristic lightshow

A futuristic lightshow that truly dances with you. Dynamic light effects and energetic strobes sync perfectly with the beat of the music. With a variety of light patterns, you can match the lighting to every mood of the night.

Up to 18 hours of playback

One charge. All-day energy. Up to 18 hours of continuous playback. Fast Charge gives you an extra 2 hours of playback after just 10 minutes of charging. Still not enough? Swap in a spare battery (sold separately) and keep the party going without interruption.

Splash-resistant design (IPX4)

Caught in a sudden shower? No worries. The IPX4-rated housing is splash-resistant, so the music keeps playing even in unexpected rain.

Smart EQ mode

Smart EQ mode automatically adjusts sound equalization based on the content you're listening to. It recognizes in real time whether it's music or speech, keeping instruments full and expressive while voices stay clear and understandable.

Control from anywhere with the JBL One app

Control the speaker via the JBL One app from anywhere at the party. Easily change tracks or adjust lighting effects right from the dance floor.

Telescopic handle and wide, sturdy wheels

The JBL PartyBox 330 is designed for easy transport. Pop up the locking telescopic handle, tilt it back on the wide, sturdy wheels, and move it effortlessly from the living room to the backyard or wherever the party takes you.

Take the party further with Auracast™

As the crowd grows, so should the sound. Pair two PartyBox 330 speakers for a wider stereo soundstage, or connect multiple Auracast™-compatible JBL speakers to build a powerful sound system for any occasion.
