Carrying case for full-size headphones?

I want to get these Monoprice 8323 circumaural headphones. As far as I can tell, they don't come with a case included. I want to make these headphones portable, so that I can toss them into my backpack and take them to campus and not worry about breaking anything.

So I need a case that will hold these. I'm having a hard time searching for a case. Amazon's search and categorizing sucks. Googling things like "carrying case headphones" brings up headphones. NE doesn't seem to offer any headphone cases at all, pretty much.

Anyone have a recommendation? I feel like I'm not looking in the right places or something.

Thanks

I wouldn't worry about it to much, They are pretty rugged little guys with decent sound to boot. Ive had them for a year or so and as long as you are not trying to break them you wont. I cant help but feel the case will cost more than the headphones.

Search ebay for headphone case and find one of the soft hard cases there for under $10. It will smell strongly of chemicals but if you let it air out for a couple days outside it will do well.
