I'm going to U.S.A. soon and there I will get myself an iPod (either a touch or a Nano, haven't decided yet). I also want to get some earphones with the iPod. Could someone give me some suggestions for a pair of earphones which can fulfill my criteria's? - In-ear (They will have to stay in when running and riding my bike up and down hill.) - Noise canceling (I am very aware of not listening to too loud music.) - Not too expensive (I'm a student.) Audio quality is less important than the above criteria's. Thank you.
