ATH-M50XWH : I have tears in my eyes...

And sonic orgasms in my ears.

These headphones are some of the clearest, nicest and most responsive headphones I've put on my head.

I've read reviews that they add some "colour" to the sound. They somewhat do, but not so much in a way that gives a false perception of how the track sounds. I'm using them as monitoring/studio cans, and they're really fantastic. Initially my recordings are being done with these and then mixed with the Yamaha HS8's. The HS8's are always a more "honest" sound in my opinion - but the sound I hear in these headphones translates very well to the track I'm hearing on my monitors, and the slight little boost of colouring they do add makes it absolutely fantastic for doing the initial recording with in the first place.

All in all, this is a purchase I would happily make again.
