Don't buy the same...
Don't even waste your time with those out of date headphones, they were new in 2001. I bought the in-ears from Apple. They take a little getting used to and you kinda have to jam them in your ear, but they sound great.
I have three sets of those "stock" headphones (from previous iPods) I use them for working out.
Spend 10 bucks more and get yourself a decent pair.
Cheers.
