Oops, didn't notice you wanted mic... These don't have a mic...
The Grado SR60 or SR80 headphones are probably the best bang for your buck...
The are about $70 and $100 respectively.
Sennheiser makes some nice one's too...
Both of these brands get pretty expensive as you go up in model
number though...
