A:AnswerYes they are Bluetooth and only require a "Pairing" to your device.... Of course they work automatically with apple products but YES you can pair to non-apple products.
This is my second pair as my new pup chewed up my original pair
A:AnswerApple doesn't give you the ability to purchase a warranty through them. I called and asked them the same question. I wanted to get AppleCare on mine and they don't offer it unfortunately. Might want to try Best Buy but I wasn't offered any when I bought mine through Best Buy. Good luck!
