Other lightning compatible DACs exist. Apple’s dongle aren’t the only hardware for using wired headphones.
If you want you can just get a lightning to usb-c adapter and then an entire world of DACs and amps are available.
When they switch to the next standard for their ports, ill finally be able to achieve my dream of getting a x -> usb c -> lightning -> aux chain set up for my car audio.
does lightning -> usb C -> 3.5mm not work? it requires an extra adapter but is better than nothing.
No, it isn't gross. Third party manufacturers both make lightning audio adapters and lightning to USB-C adapters.
