Is there an USB adapter for the Earphones that will let you use both audio and mic simultaneously for a phone conversation?
I'm not aware of a USB adapter that directly takes the 4-pin 3.5mm connector that the Apple headset uses, but you could combine one of the many USB adapters with an adapter cable like this. That will convert the 4-pin connector to the separate 3-pin stereo &amp; microphone connectors that are standard on PCs and should work with any USB adapters with an in &amp; out. You will likely lose the volume and clicker controls on the headset.
