18-hour battery life keeps the party going

Live karaoke modes & fun sound effects
Plug in your mic or guitar and take the stage. Dual mic and guitar inputs turn any party into a karaoke party while built-in vocal tuning ensures you never hit a wrong note. Have even more fun with party sound effects. Choose an "air-horn," "applause" —  even a "boo" — to get your guests cheering and laughing along. 

DJ in the dark
The control panel has convenient built-in backlighting that activates automatically in the dark, so you'll be able to keep the tunes going with no need for a flashlight. 

Get loud. Really loud! 
Connect compatible speakers wirelessly via TWS (True Wireless Stereo using Bluetooth connection up to 2 party speakers) or wired via the AUX output to another speaker.

Take a stand
The JBL PartyBox 310 is compatible with most speaker stands, so you can raise it off the ground for more visibility and even better sound. (Speaker stands not included). 

Wireless Bluetooth Streaming
Songs. Playlists. DJ mixes. Play whatever you want, however you want, from your smartphone or other Bluetooth devices. Then, connect compatible speakers wirelessly via TWS (True Wireless Stereo) using the Bluetooth connection up to 2 party speakers for an even bigger sound. 

USB playback
Pre-program your party or event with your favorite playlist from a USB thumb drive! Just pop your playlist on a USB stick and play you the tunes you love without the effort.
