Looking for earhook/clip on headphones for under $30

[Tarvaln]

I'm looking for a pair of headphones for under $30 so I can watch porn at work. (April Fools!)
It's so I can watch porn at home without my roommates hearing it. The walls are really thin.

I don't like earbuds or ones that go around the back of your head.

I saw these Koss KSC75. They seem like a good deal but I can spend a little more and would like to at least hit $25 so I can get free shipping.

Does anyone have any recommendations before I pull the trigger on the Koss ones?

Thanks
