[SOLVED] Straight Cable for HDJ-1500s?

I've noticed the HDJ-500s came with an interchangeable line cable (A non coiled one) that you could use for Non-DJ related listening. I love my 1500s to death, and I was wondering where I could find a non-coiled cable that I could use on the 1500s (Or would I have to drop $99 to buy the 500s just for that cable)?

And I think any mini-jack cable would fit the port on the 1500s, but I've had no luck finding a jack that has the 2 hinges that allow the jack to lock into the headphones.
