This is my first post, and I mostly listen to Rock (Led Zeppelin, Jethro Tull, The Eagles, Boston, Black Crowes, AC/DC, ect...), Jazz, blues, and a lot of Classical music (Mozart, Bach, Aaron Copland, ect). I really enjoy a the guitar in rock, and the strings and trumpets in classical music, and the saxophones and trumpet in jazz and blues music, so I'd like headphones that would be at those instruments. I like bass, but I do not need really bass heavy 'phones because to much gives me a headache.
I need recommendations under $200, and I'm open to buying used. From my research so far, the Sony MDR-7506's and Audio Technica ATH M50's are the most common recommendations for this price range, but I was hoping for some more personalized recommendations from you guys.
I run all my music off an IPhone 4 (I know, I know; but I'm not rich, and don't have money to blow right now), and I'm hoping to get a headphone amp as well. Any recommendations for a portable amp/DAC under $200 would also be very helpful.
