I have gaming headsets with mics and such but i recently got the Audio Techica ATH-M50s and they are MUCH better sounding than any other headphones ive ever listened to. The ATH-M50s don't come with a mic so what mic should i get? I just need one that doesn't sound to bad like echoing and things like that. I personally don't want to spend that much on one because it will just be used for talking to friends. What should i get?
