A miracle outlet and connect two RCA inputs on Hi-Fi system of your choice and voila. In addition, the cables are provided in the box. Then just select your Bluetooth music transmitter device miracle jack and you can hear music on your speakers. I use it mostly for audio podcasts that I load on my mp3 player. This is very useful to listen to the stereo. I do not put 5 stars because I have time delays in time and I guess it comes from my drive. Then I remove the WiFi connection. The cutoff still occurs occasionally. It is minimal and it does not affect me much, but it's not perfect.
