Grado headphones

I need to find myself headphones. It will help me through my days full of music. But then several questions come up. What kind of headphones do I need? Which type? What brand? What specification? And so on and so forth.

I try to browse the Internet to find the answer and I come across the page of Grado headphones. It seems like there are various types of Grado headphones with a wide range of price. I read comments from Grado headphones users and apparently they are satisfied with the quality of the headphones. Hmmm, that's interesting. I might consider to have one of them.
