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?
