Party Loud, Party Long

Got big plans that call for big sound? The JBL PartyBox 520 delivers our boldest, deepest, most powerful audio yet—complete with a vibey lightshow and next-gen AI Sound Boost technology that keeps everyone dancing. Despite its massive sound, it’s easy to move thanks to a grippy handle and wide, smooth-rolling wheels. Set it up in the backyard, by the pool, or at any location your friends drop a pin.

Enjoy up to 15 hours of playtime, plus a replaceable battery option for even longer parties. With Auracast™, you can pair two, three, or multiple JBL speakers for room-shaking sound. Whether you’re the DJ, the singer, or just the vibe-setter, the PartyBox 520 is built to bring the energy all night.
