I don't know if you would consider getting a separate mic with headphones but I recently got Audio Technica ATHm50 headphones and they sound very good and the build quality is very good. The only downside, which doesn't really bother me, is the cord is not detachable. But there is a company that sells them with a detachable cord for a few extra dollars. If you don't want a long cord they make a coiled cord version.
/edit: I was experimenting on low frequency binaural tones and 20hz was very audible. I could even hear 15-19hz tones but probably not enough to be useful.
