Keep in mind I don't factor the price into my ratings for sound, design, and comfort. I'd like to say early on that I don't pay much attention to the frequency response. I tend to prefer flat headphones, but I have no idea how to listen for "peaks", or "roll offs" and such. What I pay attention to is separation, decay, and detail. For the 65 dollars you can buy these for nowadays, these do a great job. Great addition to any collection.
