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.

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. Within 10 minutes fast charge gets you an extra 2 hours of playtime.

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.

Dual Mic & Guitar Inputs
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.

Includes the JBL Battery 400 to double the party time
Keep the vibe going twice as long by having a spare JBL Battery 400 on hand. When your rechargeable battery is running out of juice, it takes just seconds to pop a fresh battery into the slot on the back panel. Each battery has enough power for up to 18 hours of playtime, which means you could keep the party going for up to 36 hours.
