No, I'm not. I suspected this was the reason why, but I thought that maybe it was okay to use something else because the microphones are internal to the unit. Then again, the included earphones use a 4-pin TRRS connector, which I thought was strange, considering there's no mic/remote control. It's probably used for feedback control. I'll try it with the included earphones and see if it works. I'm just curious to see how well it works.
