Narrative:
When told to switch to center we complied; but couldn't reach anyone on that frequency. We switched back to departure. They told us to try again; which we did. We still couldn't reach center on that frequency. I returned again to the departure frequency; but was now unable to communicate with them.we then tried to contact center on the guard frequency using the number 1 radio. After a few minutes we were able to get in contact with them. They stated the could hear us on all frequencies that we transmitted; but we obviously couldn't hear them. We had been at 13;000 ft and center then cleared us up to 17;000 ft and on course.after a few minutes and it seeming very quiet again on center; I called them again but with no luck. At that point we had already tried all headsets and hand mikes with very limited success. We even ACARS'd dispatch to SELCAL us. We couldn't respond to them either. The captain then tried to use the mic in his oxygen mask. He was able to contact center on the number 1 radio by doing this. He then declared an emergency stating our intention to divert to a nearby airport. He cleared us to intercept the localizer for the runway there. At approximately 25 miles out; we were able to talk to the tower who then cleared us to land.
