Party loud, party long 

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. Sound might be heavy but this 400W speaker is easy to move, whether you are setting up in the backyard, by the pool, or that place where your 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.  

• Keep the good vibes going on a single charge with up to 15 hours play time. And if 15 hours of nonstop jams aren’t enough, simply swap out the replaceable battery to keep the music going. Or charge for 10 minutes and get an extra 2 hours of play time. 
• Don't worry about any splashes or spills, this speaker is designed to withstand the most raucous parties - fouls and all. JBL PartyBox 520 is IPX4 splash proof, so your flow is newer interrupted. 
• What’s better than one JBL PartyBox 520? Two or three or more! Pair them up or link them with other JBL Auracast-enabled speakers and take the party up a notch.
