I'll give a nod to Grado RS 2's. They are easy to drive and have a wonderful balance. The bass you can feel in your chest, mids are pure and the high are extended and sweet.
I listen to them for up to 1.5 to 2 hours without any problems. Later on match them with their headphone pre-amp or a tube amp and you have raised the bar progressively.
