Double the power. Double the party.

Both speakers come fully charged and ready to party — just power them on and connect your phone.

Press the Bluetooth button on the FIRST speaker, then select "JBL PartyBox 520" in your phone's Bluetooth settings.

Press the Auracast button on the first speaker, then on the second — they sync automatically. Your phone pairs to the first speaker only.

Tap once to play/pause, double-tap for next track, triple-tap for previous. Turn the dial for volume.

Press the Light Show button to cycle through patterns. Both speakers will sync their light shows via Auracast.

Plug in the power cord to charge each speaker. The speaker can also charge your phone via USB-C (cable not included).
How to pair speakers via Auracast
Press the Auracast button on the FIRST speaker, then press Auracast on the SECOND speaker — they sync automatically as stereo left/right. You'll hear a confirmation tone when paired.
How to connect your phone
After the speakers are paired via Auracast, pair your phone via Bluetooth to the FIRST speaker only — the second speaker follows automatically.
Only one speaker playing?
Your phone must be paired to the FIRST speaker (the one you started Auracast on). Check your phone's Bluetooth settings.
Speakers out of sync?
Press Auracast on the second speaker again to re-link. If still out of sync, turn both off, turn the first on, start Auracast, then turn the second on.
Battery low?
Plug in the power cord to each speaker. The speakers work while charging.
