I am always tempted to bring my A700s with me for portable use. I just could never bring myself to doing it. I don't care what other people think about me, it's just the 10 ft cord and the inability to put them anywere other than around my neck when I want to talk to someone else that's stopping me. I need a good pair of low profile, circumaural ( little bit of an oxymoron), and closed cans for outside use. After using my A700s for quite some time I can no longer stand superaural headphones, and earbuds and IEMs bug me. My Koss Pro 3s were perfect for this. They folded up so I could stuff them in my sweater temporarily, they didn't sound that bad, and were superaural. Many times I found myself blasting them and leaving them around my neck so I could here the music, and people did not seem to mind.
