Pondering the Perfect Headphones

So I bought a new iPod classic today. Now I just want to find some headphones to go with it. I’m looking for over -the-ear headphones that would be comfortable for hours each day. The last pair I had to foor the bill was the Telex Stratus 50d aviation headset that I spent $900 for. Considering I don’t fly anymore I don’t think I need to spend over $100. Any suggestions?
