I've been thinking about getting some kind of wireless head phones. I'm having trouble finding a decent pair. I have a macbook pro, so I'm assuming I could pair a bluetooth headphone to it? I was thinking about the Moto S9. But I also have an iphone and I discovered that you can't listen to music on the iphone with the S9, you can only make calls. Is there any device that allows me to listen to music on my Mac and Iphone without any adapters/transmiters or anything silly like that?
