Before you spend a boatload of money, check out the Sony MDR-7506. They are an extremely neutral headphone and can be had for only about $80 from Amazon. They are the most widely used headphones in recording studios for both music and film and have been for many years. I had this dilemma recently and can say that I will never buy another headphone as long as these stay in production. Which, based on their extensive use in the industry should be a long time.
