Yes, it's an audio plug. The original intention of it was to connect a
TDD to the iPhone, not a headset. For those still asking what a TTY or
TDD is in this case, browse here for examples:

Interestingly enough --- and I think this has been mentioned on the
mailing list before --- TTY's for the deaf and hearing impaired were
originally actual older Teletype machines. Didn't someone here on
Greenkeys do an entire history document on the development of TTY/TDD
systems?


Cheers,
Christian
