Well, they (and most other smartphone makers) "converged" all interfaces into USB-C. I personally use wireless headphones, but is using a USB-C-to-headphone-plug adapter (which you usually get with the phone) really that much of a hassle?
USB-C ports actually have to support audio (ie be plugged into a DAC). My wife has a phone with a USB-C port that gives a helpful message that it wont work without an official adapter if you plug in a rando USB-C - 3.5mm adapter. So yeah, fuck USB-C, it's a hassle.
