High quality, open-air, over the ear AND a mic...

I love my HD580's, like really a lot. I don't need them to be that good, BUT, I would love to find a headset/headphones that I can wear for many hours at a time that are also high quality.

I prefer over the ear for and not sealed, both for comfort and long listening. I find my ears tire faster with sealed headphones.

Does anything like this exist? If I have to I'd back off on the over the ear vs. on ear if they are comfortable enough.

Thanks in advance!

What do you mean you can easily put a mic on it?

If there is a good way to get a good mic on my HD580's that would be ideal!
