USB Type-C allows for analog out to a pair of dumb headphones. You can either connect a pair of native Type-C dumb headphones (dumbphones?) or a 3.5mm set of dumbphones to a $3 adapter.
There will also be digital headphones and powered dumphones, but USB Type-C can totally be used to pass an analog signal from inside the phone, directly to a tiny set of speakers strapped to your head. There's no DRM in analog audio signals.
