Auracast™ is JBL's official technology for listening with friends

Auracast™ makes sharing audio easier than ever by broadcasting sound from one device to an unlimited number of others. Imagine your Auracast™ device as a radio station, with other devices as the radios tuned in. Any audio played from a connected phone or laptop goes to the first Auracast™-enabled device and streams to others simultaneously, creating a synchronized sound experience. If you have an Auracast-enabled JBL speaker or headphones, just switch to Auracast™ mode using the triangle button, and your friends can connect by pressing their devices’ Auracast™ button. 

JBL Portable app

Check out the JBL Portable app to get updates, find product support, and unlock cool features right from your phone. You can tweak your sound with different EQ presets or go all-in with the customizable equalizer to adjust the highs, mids, and lows. This way, your music will sound just how you like it!
