AirPod PSA: apple will accept your single airpod return if you quickly buy it just to use to be able to pair your set, if you say oops you found your other one.
AirPods will only pair if you have both. If you lose one and want to pair to a new phone, you’re screwed unless you can borrow one. I bought one and told the guy my purpose and intent to return it and he advised I could not return it. I then spoke to someone else and said oops I found my other one and they did agree to refund it.
