Building a headphone extension - what cable geometry?

[rif]

First off, I'm not a believer in exotic cables or that cables, when done appropriately, make a difference.

So my qusstion is - for a headphone extension cable (1/4" female to 1/4" male, stereo), maybe 15 ft, what type of cable is appropriate: mini coax, twisted pair, straight wire?

Obviously on the twisted pair and coax, I'd tie 2 conductors together

I can't think of a good reason to use anything but an ordinary stranded three-conductor cable of at least 24~22 AWG. Flexibility and fatigue life would be the dominant concerns.

Thats what i was thinking - flexibility. I am thinking about using some bulk single conductor test lead wire from pomona or b&k, probably 18 gauge, silicone jacket.
