Features and Benefits

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 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.

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 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.

Telescopic handle and wide, 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 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, means 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

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.
