I have a two friends, each of whom runs a recording studio in the area I live in. By this I mean, an operating business in its own building, and not a basement hobby studio.
Invariably they rely on AKG K240, or similar cans. Picture a wall with a rack with a few pairs of K240's ready for use.
The K240’s are an industry standard. Keep in mind that the studio application is quite different than home listening. Some audiophile headphones may outperform studio cans on certain criteria, but by and large the studios choose something that is not too expensive, has clear sound, is reliable, and can be used for fairly high sound pressures when needed.
I have never seen anything like an HD800 anywhere near a mixing board, never mind on someone’s head during recording. In addition to good sound, look for cans that have removable cables, can be plugged into a mains powered amp, have replaceable parts, are easily serviced by the user, are comfortable, can be modified easily as needed, etc.
I would suggest going to a music supply store in your area to shop. Stay away from audiophile places. They overcharge for almost everything, and the places that sell guitars and recording gear can get pretty much anything you like, but for prices that are typically much closer to OEM.
