iPhone headphones: how does the mic work?
How is the iPhone headset picking up the microphone information and sending it to the iPhone?
How is the audio information [technically] transmitted to the iPhone? Does that mean that iPhone has some sort of chip to process information in the reverse? Does that mean the headphone port could hypothetically be used as a microphone port also [like the iPods]?
Thanks for any help 🙂
