JBL PartyBox 330 Portable Party Speaker

Bring powerful JBL sound, immersive lighting and all-night party energy to your backyard, basement, garden or next big gathering with the JBL PartyBox 330. With 280W of legendary JBL sound, deep punchy bass, crisp highs and AI Sound Boost, this powerful portable speaker keeps your music sounding big, loud and clear even when you turn up the volume.

Powerful JBL Legendary Sound

Experience 280W of powerful JBL sound from dual 6.5-inch woofers and twin 25mm PEN dome tweeters. Deep, chest-hitting bass combines with crisp highs and a wide soundstage to give everyone at the party an immersive listening experience.

AI Sound Boost

AI Sound Boost analyses your music in real time and predicts driver movement to maximise bass and volume while reducing distortion. The result is bigger, cleaner and more powerful sound that stays punchy even when the volume is pushed to the limit.

Adaptive Futuristic Lightshow

Turn your party into a dance floor with a futuristic lightshow that moves in time with your music. Sweeping ripple light trails, punchy strobe effects and multiple lighting patterns let you create the perfect atmosphere for every occasion.

Up to 18 Hours of Playtime

Keep the party going for up to 18 hours on a single charge. When you need a quick boost, a 10-minute charge provides up to another 2 hours of playback. A spare battery can also be swapped in to extend the party even further.

Easy to Take Anywhere

The JBL PartyBox 330 is designed to move with you. A telescopic handle with a secure locking mechanism and wide wheels make it easy to transport across different surfaces, including grass and sand. The IPX4 splashproof design provides added protection against accidental spills and light splashes.

Plug In & Perform

Turn any gathering into a live performance with dedicated microphone and guitar inputs. Connect two microphones and a guitar for karaoke, live music or entertainment at your next party.

Compatible with JBL EasySing Mics

The PartyBox 330 works with JBL EasySing Mics, making it easy to bring karaoke into the mix and give everyone a chance to take centre stage.

Connect More Speakers with Auracast™

Take your sound even further by connecting the PartyBox 330 with other JBL Auracast™-enabled speakers. Expand your sound system for larger gatherings and bigger events.

Smart EQ Mode

Smart EQ Mode automatically keeps your sound balanced based on what's playing. It adjusts the EQ in real time so music remains full and punchy while voices stay clear and easy to understand.

Control with the JBL One App

Use the JBL One App to control your speaker from anywhere at the party. Adjust settings, manage your music and customise the lightshow without having to stay next to the speaker.
