JBL PartyBox 520 400W Portable Party Speaker
JBL PartyBox 520 Overview
For heavy sound that's easy to bring to your next party, look to the PartyBox 520 400W Portable Party Speaker from JBL. The grippy telescopic handle and dual built-in wheels makes it easy to move around the house or travel to family and friends. Once you're at your destination there's no need to plug it in as a swappable JBL BATTERY 600 pack offers up to 15 hours of playback. Stream your playlists via Bluetooth from a mobile device, plug in a USB flash drive, connect a 3.5mm AUX-compatible component, or create the music live using dual XLR inputs and optional mics, guitar, or DJ console. Deliver vibes along with the tunes by selecting light patterns and strobe effects to illuminate the space from multi-colored LEDs that surround the dual 7.5" woofers.
AI Sound Boost
Up to 400W of audio power blast from dual 7.5" woofers and 1" tweeters. Music you can enhance with JBL's AI Sound Boost. AI Sound Boost analyzes the music you're playing in real-time, maximizing acoustic performance and minimizing distortion.
Swappable Power
On a full charge, the PartyBox 520 can deliver up to 15 hours of continuous music. If the party goes into the overtime, you can always plug it into AC power or keep things portable by swapping out the JBL BATTERY 600 for an (optional) fresh pack. If you don't have an extra battery but still need to stay mobile, plug it in for 10 minutes for a quick charge that gives you up to 2 hours of playback time.
Add More for Bigger Sound
If the PartyBox 520 is somehow not enough power for your space, you can link it to an optional second unit for a bigger soundstage and true stereo separation. For the biggest events, you can sync the PartyBox 520 with other JBL Auracast-enabled speakers.
