    "The output audio is not sent to the speakers, but from the
      headphones, and the mic cannot pick up the played audio from the
      air" - actually, it can. I recently tested a USB audio interface
      with connected to it XLR microphone, and I was wearing circumaural
      headphones. With high enough gain I managed to obtain oscillations
      because of the acoustic feedback.

              The output audio is not
                sent to the speakers, but from the headphones, 
              and the mic cannot pick
                up the played audio from the air, 
              so I don't think it's an
                echo issue.
              

              I am using a four-section
                headset, and the input and output are on the same audio
                port. 
              Is it possible that there
                is signal interference in the input and output?
              

              Thanks,
