Product information

Get the party started

Kickstart your night with the JBL Partybox 310 Bluetooth Megasound Party Speaker. From EDM to hip hop, you get loud, powerful sound and punchy bass without missing any of the details – all thanks to JBL Pro Sound.

And since it's portable, with a rechargeable battery that lasts up to 18 hours, you can take the party outside, to the park, or to your mate's place. The integrated wheels and handle make it easy. And thanks to the IPX4 splash protection, it's perfect for the poolside.

Play music wirelessly

Everyone can have a go at being the DJ thanks to the Bluetooth connection. Sync up a smartphone, tablet, or laptop to the Partybox 310 and play tunes straight from your favourite streaming services. Or just preload a playlist onto a USB stick and hook that up to the Partybox 310.

If you find your phone running out of juice towards the end of the night, you can use the USB port to recharge.

You can also plug in a mic or a guitar for a lively jam session or impromptu band practice.

Create that party vibe

With five different light modes you can really set the vibe with the Partybox 310. For extra sound power, you can connect another JBL Partybox speaker wired or wirelessly. You can control the music, lighting and sound effect using the JBL Partybox app on your phone.
