Ok, I need some advice. I never owned a good headphone before, I'm looking for a circumaural headphone that doesnt need a amp on the range of $200~$400. I'm only gonna use it at house so I guess a open-back is better since I dont care about sound leakage. I listen to a lot of kinds of music. I'm researching and HD 598 looks like a good pick, but are there better options?
