JBL PartyBox Stage 320

The JBL PartyBox Stage 320 is built for people who want real party energy without being stuck in one place. It pumps out powerful JBL Pro Sound with deep, thumping bass that fills both indoor rooms and outdoor spaces. An adaptive lightshow of swirling starry lights, cool trails, and strobe effects moves with the beat, turning any gathering into a visual experience. With a solid telescopic handle and wide sturdy wheels, you can roll it almost anywhere, while the splash-proof design (IPX4) means a little rain won’t stop the fun.

Up to 18 hours of playtime keeps the music going long into the night. When the battery runs low, simply swap in a fresh replaceable one and keep the party rolling. Dual mic and guitar inputs let you jump on stage for karaoke or live performances, and interactive party effects give you control over the vibe. For bigger crowds, Auracast support makes it easy to wirelessly link multiple compatible JBL speakers.
