There's very little more enjoyable than walking around the city on a nice day listening to music. Now that Spring's finally really getting underway, we expect to do that much more in the coming days. In order to do that, though, you need to make sure you have some headphones (and comfortable sneakers). If you're still rockin' with the ones that came with your iPhone or iPod, and want something a little better, we got you. The good news is you can get some headphones that are a lot better for a little money. For those of you that don't like walking around looking like you're DJing a party, we've put together a list of our favorite in-ear headphones currently available for under $100.
