A:AnswerContact apple to get a replacement for free.They will charge you at first but after you return the airpods that arent working properly your money will be refunded to you.
A:AnswerYes. No wires, works with Bluetooth to a device like iPhone, Chromebook, etc. I love them... am listening to War and Peace while working around the house doing laundry, dishes, meals, etc. I just need to be in range of my iPad, for me about 20-30 feet. Bonus - you can set it up in settings to tap one EarPod twice to pause, then double tap again to play. Or the other EarPod to tap once to forward a song / track.
A:AnswerTo your Apple TV device, yes. When I turn on my tv it wants to pair to the Air Pods.
