These headphones are really famous and a lot of people recommend them--that's why I bought them for mixing. I wouldn't say they are perfect, my expectations were higher, but still, I not regret buying them: nevertheless, it's a GOOD choice. I use them with my UAD Apollo Twin sound interface and everything works fine, I have enough of headroom.
Pros:
+ clear and detailed sound
+ interchangeable cable
+ nice look
Cons:
- seemed to me too bright - but it's good for finding sound artifacts
- not so comfortable, a bit tight - after an hour of using them I had a headache (hope some time needed for them to loose up)
- the cable is not coiled (I believe the majority of sound engineers prefer a coiled one, as I do)
