I used to be on that headphone jack hill until my headphones died. I then realized, that the market for "normal" headphones, i.e. the ones you just hang in your ears and not the ones you ram into your ear canal, has simply died while I wasn't looking. I've switched to Aeropex and have never been happier. I still think removing the jack was a stupid "hey look, we can do what Apple does" kind of move by nearly everyone, but I now can accept it and live with it.
The headphone market is booming though. Headphones like the Beyerdynamics DT 770 PRO, so the big ones, are more popular than ever. It's true that for the small wired ones that go in your ear, the ones that go more into the ear canal than sitting near it seem to be more popular right now. But the other kind still seems to be very popular, Apple has their cultists convinced those are the best thing (I'm kidding, no position on my side what's better, but they are sold a lot because Apple sells them). And there are many alternatives on the market. I could buy the Sennheiser MX 375 right now. Where did you get the impression that that category is dead?
