Earphones/Headphones

Hey guys. Just curious as to what earphones or headphones you guys use and what you recommend. For obvious reasons most shops do not allow you to test them before buying so the only way to really gauge how good they are is through first hand experience from others. I have a set of Sennheizer Mx 581's that I use at work which I'm thinking of replacing because I want something with a bit more noise isolation so others in the office can't hear what I'm listening to and also my current ear phones tend to hurt my ears after long periods as in they become uncomfortable. I've tried those in-ear ones years ago but they also tend to be uncomfortable and never fit properly in my ears and they keep falling out. Any recommendations?

At home I have a set of Sennheizer HD201's hooked up to an old NAD amp that I use when I'm busy on my home PC. They're an awesome set of headphones for the price
