I have a pair of earphones for my iPod that are good at blocking out background noise (they have little rubber in-ear things), but this is useless at times because of the noise generated by wind rushing past the cables.  For example, when skiing, as soon as I get up to any speed, any music I am listening to is drowned out by the whistling of the wind.

I think there should be a simple solution to put a sleeve around the cable (some sort of stretchy fabric tube I'm thinking), to reduce the volume of the wind disruption, by sheltering the actual cable from the wind.  However, I can't find anything on the internet that looks like it would do the job.

Has anyone got any suggestions of how I might solve this problem, or what I could use as a sleeve for the cable?  It doesn't seem like it would need a very complex solution, but there don't seem to be any out there...
