General Features

Rock out with powerful JBL Pro Sound from two 6.5” woofers that deliver clean, precise, deep bass even at top volume and a pair of 25mm dome tweeters that produce crystal clear highs. Indoors or out, you can fill a space the size of a tennis court with music.

Take all that sound and add a thrilling lightshow featuring starry lights, cool light trails, and strobe light effects—all synced to your beat.

Party from dusk till dawn with up to 18 hours of play time on a single charge. And if that’s not enough, just swap out the replaceable battery* and keep on dancing. Or if you just need an extra boost, 10 minutes fast charge gets you an extra 2 hours of playtime.

Roll up to the party with wide, sturdy wheels and an easy-to-grip handle that telescopes up when you need it and down when you don’t.

Whether you’re partying with friends in the park or by the seaside, the JBL PartyBox Stage 320 is IPX4 splashproof, means a little rain won’t stop the fun.

Get the most out of your speaker. AI Sound Boost analyzes the incoming signal in real time while simultaneously using an AI algorithm to predict loudspeaker movement and power response. It pushes the driver to its maximum capability, fully exploiting the dynamic range for better and more powerful sound. It also reduces distortion even at high volume, maximizing the bass output and overall loudness.

Want even more roaring Original JBL Pro Sound? Stereo pair two speakers for a wider sound stage. For your biggest events, multiple JBL Auracast-enabled PartyBoxes can be connected wirelessly using Auracast™.

Bring live talent into the mix. It’s easy to sing and play along using the guitar and dual mic inputs. With karaoke EQ tuning and the built-in lightshow, everybody’s gonna sound—and look—like a superstar.

The JBL PartyBox app makes it easier than ever to add interactive party effects, control your music, adjust EQ settings, and customize the colors and patterns of your light show for the perfect party vibe.
