I've been reading the posts about people losing an Airpod, and thinking "who would be stupid enough to do that?" - well that would be me. I've been using either Airpod from time to time as a bluetooth headset (one at a time). I set one down somewhere, it ran out of juice, and I cannot find it, even though I've looked EVERYWHERE. Apple has announced that they will sell you a single as a replacement, but be prepared for noone at Apple knowing this. I spoke to 3 different people at Apple Support, each of which told me you could NOT buy a single, until I found this link with the info on Apple's own site: https://support.apple.com/iphone/repair/service/pricing Once I started showing them this, they were willing to do some work to figure out the process. You have to go into a store, and take your original box, in order to place an order for a single. There is no delivery date expectation at this point. Good times. In the meantime I'm continuing to use my existing single.
