I am looking into buying some extremely high quality headphones. I've looked into a small variety so far of the high-end, DJ headphones and have come across the following: SONY MDR-7505 (My friend has a pari of these and I love the quality) SONY MDR-V900 SONY MDR-SA3000 I'm just looking for everyones recommendations. Which would/did you choose? Were you happy? Would you change? I really want to get the best if I am going to be paying a lot of money. Feel free to suggest new brands/models. I want the highest quality experience I can. Some headphones that will allow me to sit back and really listen to the details of a song. Thanks, Nat.
