JBL PartyBox 520 Portable Battery-Powered Party Speaker with Powerful and Loud Sound

Electrifying sound with AI Sound Boost

Feel your music surge. The JBL PartyBox 520’s AI Sound Boost analyses audio in real time and lifts loudness and clarity without harshness, so vocals cut through, bass lands with intent, and every beat arrives bigger, cleaner, better.

Futuristic lightshow

Lights that move like your favourite track. Dynamic patterns, pulsing strobes, and a bold ring of colour sync to the music for any mood — hype for workouts, chill for nights in, neon for weekend blowouts.

Up to 15 hours of play time

Keep the vibe alive for up to 15 hours on a single charge with this party speaker. Need a longer run? Swap in a replaceable battery and carry on, or grab a 10-minute quick charge for an extra 2 hours of play time.
