Hi, I'd like to know if I can connect wired earphones to the new iPad Pro, and what kind of connector is required.

I understand, it’s just that those adapters don’t work well in my experience. I was looking for Apple branded headphones with a usb-c connector. So, I guess I’ll go with another headphone vendor:

Actually was wondering if usbc (TB4) connector based headphones were supported?

Also, there is no 3.5mm connector shown on the diagram in the apple store.
