500+ Head-Fier
This maybe a dumb question, but I figure I ask rather than trouble shoot it myself and figure it out the long way. They don't say talk is cheap for nothing.
Anyway I normally don't use mics on headphones so I don't know if I'm suppose to hear myself on my headphones through the mic. And the mic is mono channel so does the amp that feed the mic audio back to the headphones just duplicating it? And furthermore most mics on headphone cables are single ended termination so the ground is pretty obvious to figure out. But what about when the headphone is balanced which ground do you use and do you send the audio back out to the headphones and do you have to worry about echo cancellation. I know intercom systems and cellular handset that supported speaker phone option ran into these types of issues. These may be ancient digital artifacts, but could may well be relevant to the future if people forget things.
