If you are like me and cannot get the regular iPod headphones to fit in your ear properly, then instead of spending a lot more money on another pair of headphones you could just buy one pair of yurbuds and get the ones you have to sound even better.  They are customized to your ear so like some $1000 pairs of in ear headphones I have seen, they are made just for you.  This means that you can wear them comforably for extended periods of time and you can play your music for longer because it allows you to operate at lower volumes.  Check out the site and find a local retailer where you can check them out.
