Electric sound with AI Sound Boost

Powerful sound that will make your playlist shine. This sound is designed to match your energy, so you feel like every song is being performed live. Turn it up and your music will still sound amazing, as our new proprietary technology, AI Sound Boost, analyzes your music in real time to deliver maximum acoustic performance with less distortion.

Futuristic show with lights

Did someone say light show? Dance all night with dazzling light patterns and flash effects that create a unique atmosphere at every event.

Up to 15 hours of playtime

Keep your good vibes going with just one charge, with up to 15 hours of playtime. And if 15 hours of nonstop music isn't enough, simply replace the replaceable battery to keep listening. Or charge it for 10 minutes and enjoy 2 extra hours of playtime. *The additional replaceable battery is sold separately.

Features

Multiple speaker connection via Auracast™

Bigger parties require even more powerful sound. Pair two PartyBox 520s for a truly stereo atmosphere via Auracast™ or wirelessly connect multiple JBL speakers with Auracast™ capability and let your music grow along with the size of your party.

Control your party directly from the JBL PartyBox app

Don't feel stuck babysitting the speakers. Control your music, equalizer settings, and lightshow from the JBL PartyBox app, wherever the party takes you.

Telescopic handle and wide, sturdy wheels

Wherever you go, the JBL PartyBox 520 is ready for action with an extendable handle and rotating wheels for smooth transportation.

Powerful party, endless party

Do you have big plans that require powerful sound? The JBL PartyBox 520 knows how to set the mood with a vibrant light show and our loudest, boldest, most powerful sound yet, featuring brand new AI Sound Boost technology to help you move and groove. Our sound may be heavy, but this speaker is easy to move, whether you're setting up in the backyard, by the pool, or in the spot where your friend just dropped a pin. Every move is smooth with the PartyBox 520's durable handle and wide wheels that are ready to roll when you are. With up to 15 hours of playtime, you can throw plenty of parties before it's time to recharge. And don’t worry about splashes or spills—this speaker is designed to withstand even the wildest parties, mishaps and all. What’s better than one JBL PartyBox 520? Two, three, or more! Pair them up or connect them with other JBL speakers with Auracast™ capability and take your party to the next level.

    PartyBox 520. Purchase 29/05/2026. The device is a beast. JBL sound, super bass. Maybe I wanted a bit more volume, but for that you go to more professional and much heavier machines. The device at 25 kilos can be taken anywhere easily.

    Amazing speaker, truly unbelievable how loud it plays for a portable with a battery
    and the most amazing thing is that it has autonomy so you can easily have 2 parties, not just one, because even at high volume it plays for 8-9 hours

    I highly recommend it
