You are 100% right about that. It was a bad idea on my part to use it as an example (it was the first that came to mind, from my recent memory). Can't quite remember which other manufacturers actually burned every single unit before putting it on the market, but I guess that's irrelevant now. As for whether it makes sense for the manufacturer to factory burn-in their earphones... well... I don't know. Maybe that's asking too much from an $200 IEM. My only problem is within the belief that burn-in fixes "intended" tuning, where it simply doesn't.
