I got it from Hong Kong long ago for my UE TF10, it's a factory made cable from Japan. These days Oyaide still keep their products made in Japan I believe and I'm a big fan of them. Not because they're the best, but no doubt their cables offer reasonably good sound quality under an affordable price, ebay has a lot of them and the prices are pretty close to mine. Otherwise, you can look at Oyaide website to find the closest dealer near your place. For the cable itself, you'll have to modify the connectors yourself in order to fit ASG, so please keep that in mind.
Compare to the stock cable, Oyaide provides a hint more of details and highs with tighten up bass, but the stock one has a more tender vocal presentation and wider soundstage in my opinion. I have to say actually the stock cable is a pretty decent one and honestly I prefer it's appearance over the Oyaide. Oyaide cables do have a specific sound character, so whichever cans you attached to it, you're pretty much listening to Oyaide rather than the original sound of your phones, some people may not like that. One more thing, the UE Oyaide tends to be quite stiff and springy when it's new, it's not that easy to keep it around your ears if worn over-ears.
