I'm in need of some earphones that stay in place when you are running or when you turn your head to look for cars. I don't have an iPod right now, just a Rio that holds six songs , but I will be getting one in the next 3 or 4 months so I want to get something that sounds alright. I don't really want to spend more than $40. Any suggestions? Or, do the ones that come with the iPod stay in while running? If so, I might just get some $10 ones to hold me over.
