Comfortable Stealth Headphones?

rhetoric asks: "I work in valet parking, and I got an iRiver unit for Christmas. This is great because I can listen to music in one ear while parking cars or in both ears while idle, and with the right headphones, no one can tell I'm wearing them underneath my coat and hat. The problem is that the iRiver headphone cord is horribly short and poorly proportioned, and the headphones are rather uncomfortable. Could anyone recommend some comfortable yet small headphones that wrap around the back of the head, so that the cord can go down the back of one's neck?"
