I have a pair of philips headphones with an in-line mic. I also have many pairs of earbuds with in-line mics. What I want to do is have my philips headphones as my audio output and use the in-line mic on another pair of earbuds as a mic. The problem is when I plug the earbuds into the mic input it uses the earbud part rather than the built in mic. Is there any way to fix this?
