Sony MDR-V150's. You can get a pair for about $25.
I've owned a half-dozen of these over the years.
They sound great, but they need to be carefully handled.
Every pair I've owned has broken the exact same way.
They have improved the durability of the design over the years, but you can't just toss these around.

Or...JVC HARX300's. Those go for a shade under $20.

I buy headphones on a regular basis from Burlington Coat Factory.
You won't find recognizable brand names there, but you can get a quality sound for a cheap price.
I routinely buy headphones and earbuds there for $10 or less.
Just bought a pair of "over the ear" iVibes that I love. Great mid-range and low end.
They leave a little to be desired up top, but again they only cost $11.
