Question about using with Beats wireless headphones

I have a 7G Nano and am using it with a new pair of Beats Studio Wireless headphones. I did the initial bluetooth pairing and have used the headphones with the Nano a couple times in the gym with good results. But each time I have fumbled with buttons and settings getting the music playing. I read instructions in the Nano manual; also read Beats instructions but they are not very clear.

The Nano is already paired with the headphones and they are the last device I used with it. I turn the headphones on. Then, do I have to do something with the BT connection settings on either the Nano or the headphones or should I just be able to turn on the Nano, hit play and be up and running? If one of you already uses this combination, then I would appreciate it if you could just tell me the procedure each time you start using them.
