I have an iPod Shuffle that I got for free from this deal. The earbuds that come with it hurt like hell in my ears (am I the only one?). Right now I have a pair of Sennheiser HD-202's connected. Obviously there is a considerable bigger driver in the HD-202's. My question is how much faster will my batteries go dead vs. having the supplied earbuds plugged in?
TIA.
