It for hands free conversation from your cellphone. I don't think there is a way to do just music. I really don't know that answer. It was dads when he drove in the car for hands free. Sorry I couldn't give a better answer.
I had to talk to a family member about thus device because I did not know much about it. It was listed wrong. This is not a Bluetooth for cell phone it is amplifier for hearing. Sorry about listing wrong
I wanted to change the description to amplifier but it is bring bid on. I will refund the credits sorry about this. It is Amplifier not a cellphone hands free device.
