A:AnswerYes. Wireless Beats by Dr. Dre Headphones and earphones work with bluetooth enabled devices. For iOS customers - once paired, your headphones automatically pair with your other iOS devices that are signed in to iCloud and using iOS 11 or later, macOS Sierra or later, or watchOS 3 or later and you can switch between devices connected to iCloud without having to re-pair.
A:AnswerYes, they seem to be. But they say they are refurbished, but I in my past experiences, I would have to say they lightly check them. I can wear them for about 1/2 hour before they start acting up.
