I have a great pair of closed headphones that I really enjoy (COP) for all around listening at work or home. I am considering a pair of open headphones for home listening. I generally listen to rock (old/new), country, and jazz. I have a pair of Sennheiser HD495 that are on ear style, but I don't really care for them. They sound muffled and constricted compared to my COPs. I run them through a FiiO E17. What are the reference headphones in this category, price range and type of music?
