To my mind I have the perfect headphones. Headphones are vital in recording (as well as listening to music-you have a mind then that listens to nothing else-it picks up so much more of the detail that you have not heard before). I have no idea of the price of them in USD-probably cheaper as usual but I got them for £70, were £90 (enough said-I know a few people after spending thousands-they obviously pitty me)-but to invest in these would be worth it-as long as you keep them well maintained they will last. They are on the border line of proffesional obscene priced headphones and the top quality self-recording with their diffused feild etc. Buying a pair of these in my opinion is more important than buying good monitors as the detail is picked up.
By spending say $90 instead of $30 you could be saving money especially in the long run.
By the way-it's been a while since my last reply-have you bought any yet out of interest?
If you are looking for good quality, affordable headphones, the Audio-Technica ATH-M40fs are outstanding, and can be had at zzounds for $60--they were around $100 everywhere until zzounds for whatever reason dropped their price a month or so ago.
