Got big plans that call for big sound? The JBL PartyBox 520 is a portable party speaker built to match your energy—400 watts of bold, chest-thumping audio powered by AI Sound Boost, which analyzes your music in real time to keep things loud and clear without the distortion. Two 7.5-inch woofers and dome tweeters bring the kind of deep bass that makes every song feel like a live performance. Rolling up to the backyard or a tailgate? Extended telescopic handle and wide sturdy wheels make moving this outdoor speaker surprisingly smooth. Once you're set up, the music-synced light show takes over—glowing patterns and strobe effects that turn any space into something worth showing up for. And from wherever you're standing, the JBL PartyBox app puts full control of the music, EQ, and lightshow right in your hand. Up to 15 hours of playtime on a single charge keeps the energy going deep into the night, and if that's still not enough, the replaceable battery means the party doesn't have to stop for a recharge.* Want to go even bigger? Pair two PartyBox 520s via Auracast for true stereo, or link additional Auracast-enabled speakers and let the sound grow with the crowd. *Additional replaceable battery sold separately. With the JBL PartyBox 520, we carry the mood and the energy—everywhere we go.
