Beherdynamic DT 100s but they're kind of uncomfortable. Squeeze your head really tight!
They're cheap enough too.
And they can take a lot of crap... I dropped 'em in the sea once. Seriously. Had to dry them out with the heater of the car. Thought the salt water would ruin them but they were perfect.
You may ask what I was doing with headphones like those on the beach? I was recording the sea of course! Then there was a storm, I nearly got drowned in a cave, a big wave crashed in on top of me. I made a run for it and the headphones fell off my head and got almost carried out to sea! Scary 'coz they weren't mine.
