Best Sealed/Full-Sized/Balanced Headphones for iPo

I'm not a big fan of putting things into my ears, unless it's my finger. I've been using the B&O A8 earphones for some time now but really want something that fits around my ear, rather than goes into my ear. I also want to be able to use it with my iPod, preferably without having to get an amp. I'm open to suggestions though.

I was at the Apple store yesterday and listened to the Bose around-ear headphones and thought they were quite nice. Then someone whispered in my ear: "No highs, no lows, must be Bose."

At one point, during a daydream, I thought about getting the AKG 701s, a Simple iPod amp and calling it a day. I'm a software engineer and work in a cubeless environment so it would be rude of me to force others to listen to my music.

Thoughts, hazings and suggestions are always welcome.

Thanks,

Jon
