Product Features

Powerful JBL Pro Sound

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

Futuristic Lightshow

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

Up to 18 Hours of Play Time

• Party from dusk till dawn with up to 18 hours of playtime on a single charge. If that’s not enough, simply swap out the replaceable battery* and keep on dancing. Need an extra boost? A 10-minute fast charge gives you an additional 2 hours of playtime.

Telescopic Handle and Sturdy Wheels

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

Splash Proof

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

AI Sound Boost

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

Multi-Speaker Connection by Auracast™

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

Dual Mic & Guitar Inputs

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

JBL PartyBox App

• 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 lightshow for the perfect party vibe.

Made in Part with Recycled Materials

• The JBL PartyBox Stage 320 incorporates post-consumer recycled plastic and is packaged in FSC-certified paper printed with soy ink.
