I’ve had my fair share of expensive wired headphones, I have no doubt that there are still use cases for wired ones and that some people prefer them. But it’s just so much more convenient to not have the cable there anymore. The amount of times I got stuck on door handles…
Seeing wired headphones on people has definitely declined drastically in recent years. It’s one of those societal changes that make movies from that era look really dated.
Besides, I’m sure the really high end of headphones is mostly wired, but just because headphones are wired doesn’t automatically make them superior to any wireless one. There’s shitty ones and decent ones on both sides.
