Think about Seekers post, before comparing.
Again; you don't want headphones that make things sound 'better'.
You want headphones that help make the mix you create sound good on most other systems (translate well).

I have 'phones that sound "better" than M40's (including M50's on some songs).. but I don't trust them to give me an 'honest' mix that sounds good on other systems. Not for anywhere near this price range anyway ..

I do not work here, but the benefits are still awesome
Make your sound your own!
