I bought this so I could start running again and listen to my iPod Classic. My iPod fits perfectly, this case grips it so it doesn't jump around and the headphone jack is easy to reach. I'm also relatively slim so it fits my arm very well. I would definitely recommend this to any active person looking to listen to tracks while they work out, jog, run, or even do push-ups. Great product that shipped fast, and for a good price.
