Noisy earphones


I use Etymotic Research ER-4S in-the-ear earphones with my iPOD Nano when I walk, but it's annoying that the earphones transmit sound thru the wires/cord. I can hear anything that touches the cord. For example, when I walk, I can hear the cord thru the earphone as it rubs or bounces against my shirt or jacket. It's almost like there's a live feed thru the wire. There is no short that I know of. Could it be that the earphone plug is not grounded with the iPOD and that I need to use an additional jack to properly ground it?

it's a mechanical sound x-fer dude. you can only avoid it by not touching wires. i guess many folks who excersise with earphones hear wire tapping through their headphones.
I have found the shure IEM's to be quieter when exercising--but they all have some issues this way. Go to www.head-fi.org and read till next week about this issue and what people have found and preferred. At the gym, my shure 4c are the quietest I own.
There is a cord relacement available, IIRC, that addresses that problem. BTW, with the nanos, w/o an amp, you might be better off with the 4p(ortable).
Thanks much!
