I mean, I'm not sure you'll ever come back, there's been plenty of drivebys by people like you who clearly haven't read the thread so this is probably pointless but... AirPods are not super expensive and they've been selling incredibly well.
I don't doubt they are selling well (well, I do doubt it. This seems like a niche product). I have no clue about the sales numbers. But Apple does discount stuff that doesn't sell well from time to time.
Considering Apple's usual margins, they are very likely massively overpriced. That's how Apple works. $160 earphones that are going to last about two years don't seem like a wise purchase.
