Hi, if anyone could help me. I'm thinking about buying an AW series 2 so i can go runnning without my iphone. I use the Nike Run Club app. Can i listen to the music that i had sync'd to the AW? Because on nike's website it says that it plays the music through the phone, so technically i would have to carry my phone with me. But can't i just leave the music playing on the background and use the nike app at the same time or other apps? thanks in advance for the help.
