A:AnswerI have the pixel as well , and I've been using it with my airpods for about 2 weeks now and I love them ! I was having an issue at first with the airpods playing music at a really low volume , but I found a workaround in the Bluetooth settings ( just a few Google and Reddit searches ) ... Overall I couldn't be happier ... Besides a few connecting and unconnecting issues , and the occasional situation where the person I'm on the phone with says the airpods are picking up too much ambient noise around me , they have been great .
A:AnswerIt won’t work on what you have. You can purchase a Bluetooth adapter for your iPod but a lot to carry so trade in and get a iPod with Bluetooth
A:AnswerIf the Kindle fire had Bluetooth headphone capability the shouldn't be any reason you can't use these. They work like any other set of Bluetooth headphones with non Apple devices.
