anybody know if the new in-ear headphones will work with older (5G, 2G nano) ipods? I want a shuffle for working out, as my arm gets sore after an hour of carrying my nano on my arm? i want the shuffle, but only with the in-ear phones. however, I want to be able to use the earphones with my older ipods. I don't care whether or not the controls work, just as long as i get sound. edit: now I feel like an idiot. It says right on the product page that audio works on all ipod models. this is what happens when you don't search first.
