Podcasts are a great way to get news while riding. One little gadget I've found invaluable for my commute is the remote. It allows me to make sure the volume is at the right level (i.e. not too loud). If you're concerned about not blocking out noise, steer clear of in-ear earbuds and just stick with regular ones. They stay loose enough in your ear so you can still hear what's around. iPod or creative, both are good.
