content: Bought these for sporting purpose as i like to cycle and go to the gym weekly. Good sound but only stays in my ears for 30 seconds at a time. Cord is too short to have an IPOD in your pocket and the extension cord is too long to have in your pocket. I am not happy with them at all and i strongly recommend not to buy them, The CX500 is much better and more feasible for athletics or general use. Thank you - John
