Description
Room-filling JBL Pro Sound
The JBL PartyBox 520 is a portable, battery-powered party speaker built around JBL Pro Sound. Dual 6.5″ woofers keep bass clean, precise, and deep even at maximum level, while two 25 mm dome tweeters carry crisp highs—enough output to cover indoor or outdoor areas roughly the size of a tennis court.
AI Sound Boost helps deliver strong, electrifying party-level volume.
Beat-matched lighting
Starry lights, flowing light trails, and strobe effects run in sync with your music for a coordinated show indoors or outside.
Power that lasts—and swaps
Expect up to 18 hours of playtime on a single charge. The replaceable battery can be exchanged for a spare to extend sessions (additional replaceable battery sold separately). Need a quick top-up? 10 minutes of fast charging adds about 2 hours of playtime.
Scale the party wirelessly
- Auracast: Link two PartyBox 520 units for stereo, or connect multiple JBL Auracast-enabled speakers as your crowd grows.
- JBL PartyBox app: Change tracks, EQ, and lighting from your phone instead of staying at the speaker.
