I suppose it wouldn't hurt for me to re-mention the no-name cable I've been happily using with my M-100 for many months now. Picked it up on ebay from the seller
worth-buy -- the current listing is
this one (under the heading "Universal JACK 3.5mm Stereo AUXILIARY CABLE CORD CAR AUDIO AUX WIRE Male to Male" in case the listing expires and someone needs to do a search).
I bought mine because I was looking for a basic, mic-less, button-less
entirely black cable in a sensible length (V-MODA's audio-only cables are too long for me to use portably without resorting to obnoxious bundling tactics) to match my Matte Black M-100s...and it's done its job admirably.
Lightweight, markedly less microphonic than the stock V-MODA cables, and with no degradation in sound quality that I can sense. Note that the ebay description says they're 38 inches long, but mine (I've purchased a few) are actually 48" tip-to-tip, which is perfect for my needs. The black version looks to be out of stock at the moment, but hopefully that's just a temporary thing and not a NuForce-style discontinuation issue.
The only downsides to the cable that I've encountered are: 1) I needed to rub the metal plugs with a cloth initially to remove whatever invisible factory coating made them sound scratchy when rotated (much like some of Sennheiser's brand-new IEM cables), but once that was done, the problem has gone away; 2) like many cables, I did notice it stiffening in some of our extremely cold Boston weather this winter, but not to the point that microphonics were a huge issue; and 3) I would have preferred a right-angle termination at the source end, but no dice.
Here's a quick pick of it (and a right-angle adapter) in action:
