On BT supported Receiver/Amplifier: 

Pair “Woojer” to your smart Receiver/Amplifier. 

Note: Since different Receiver/Amplifiers operate differently, please refer to your specific Receiver/Amplifier manual to find out how to connect a BT device to your Receiver/Amplifier.

If your Receiver/Amplifier does not support BT: 

Use an external BT transmitter. Pair “Woojer” to the transmitter and connect the transmitter to your Receiver/Amplifier audio output. On your Receiver/Amplifier enable output both from the speakers and the headphones.

*Note: set your headphone audio source to HIGH volume.
