C1000/3x00 Hardware / What Headphone With Microphone For The Cxx00?

Hi,
if really works with a stereo headphone, then you're absolutely right (I never checked that). Anyway, the important thing is, that handsfrees with 3 rings do work ;-)

QuoteFor those who are wondering how the switch between audio input and output is done: It's done via the different impedances of headphones and microphones.

Sorry, but that cannot be exactly correct.
I think the switch is done in software (dependent on the kind of software it either uses the channel as input or as output).
Reason: I can also use normal stereo earphones for KPhone/PI and use one of the earphones for listening and speak into the other one. Works well, too, but not optimal. So the decision if a mic or headphone is connected cannot be done via impedance measurement.
