As I use both of these Incase Arm Sport Bands, in this demo, I take you through a physical description of both of the iPod nano 7th generation and iPhone 6s  Arm Sport Bands available from Apple Stores or online.

I just find these cases handy to use by getting your iPod nano or iPhone out of the way when exercising, gardening etc, and with the use of Bluetooth ear phones, you don't have any wires to worry about.
