Overview

Got big plans that call for big sound? The JBL PartyBox 520 knows how to set the mood with a vibey lightshow and our biggest, boldest, thumping sound yet, powered by the all new AI Sound Boost tech to help get everyone moving and shaking. Our sound might be heavy but this speaker is easy to move, whether we're setting up in the backyard, by the pool, or that place where our friend just dropped a pin. Every move is smooth with the PartyBox 520's grippy handle and wide wheels that are ready to roll when you are. With up to 15 hours of playtime, you can host multiple parties before it's time for a recharge. And don't worry about any splashes or spills, this speaker is designed to withstand the most raucous parties - fouls and all.

What’s better than one JBL PartyBox 520? Two or three or more! Pair them up or link with other JBL Auracast™-enabled speakers and take the party up a notch.
