PartyCast wirelessly synchronizes your music across an almost unlimited number of PartyCast-compatible speakers. 

If you are unable to enter PartyCast mode, please try the following steps:

1. Reset the Soundcore 3 speakers by holding both Power and Volume+ buttons for 5-10 seconds. 
2. Connect the first speaker with your Bluetooth device.
3. Press and hold the Bluetooth button on the Soundcore 3 for more than 3 seconds. The Bluetooth LED indicator will flash white slowly.
4. Press and hold the Bluetooth button for the second speaker to enter PartyCast mode. Once the LED flashes white slowly, double-tap the Bluetooth button until the white indicator flashes quickly. 
5. When successfully connected, the LED indicator on the primary speaker will continue flashing white, while the LED indicator on the secondary speaker will be a steady white. Audio from the speakers should play in unison to confirm PartyCast mode has been successfully enabled.
