sennheiser HD280 pro is one of the good choices,
you want a headphone that does not press up against
the earlobe. You want the headphones to cover the entire ear, like a cup.
You will need loudspeakers to mix by, you really don't want to mix something that will be played on car radio- with headphones, the sound will be all wrong.
It can be painful to use a headphone that presses against your earlobe, for several hours.
