Our take on the JBL PartyBox Stage 320

The JBL PartyBox Stage 320 is a 240W RMS portable party speaker with a rechargeable, replaceable battery, a telescopic handle and wheels, and an adaptive light show synced to the music. It adds mic and guitar inputs, a built-in power bank and Auracast multi-speaker pairing, and it is rated IPX4 for splashes. It suits hosts, DJs and outdoor gatherings that want loud bass and lights without a mains outlet. Against smaller PartyBox models it is heavier and larger but plays louder and runs longer; against premium party speakers it gives up some refinement and app depth but keeps the rugged, wheeled format. Owners rate it highly for volume, bass and battery life.
