Having recently purchased these headphones I was very sceptical about all the good reviews due to the unavailability to actually try them as no retail stores or good hifi shops seem to sell them. I decided to bite the bullet and puchased a pair, all I can say is WOW.
They have exceptionally good clarity good soundstage and very detailed sound.Some reviews found them to be uncomfortable, this was true at first but as with every thing new once they are worn them in I don't even notice them.
I use them from iTunes and find the EQ settings are responsive to get the sound just right.
When listening from a 5th Gen Ipod they sound great.
Plugging them in my amp hooked up to a nad cd player send them to a whole different level.
I find the Bass to be very good and controlled (no thuddy muddy sound)
The best way to describe the sound difference from standard Headphones is like going from VHS tape to Blue-Ray discs, The amount of detail you get at first is overpowering but after a reasonable burn in time (20 hrs in my case) not only do you become accustomed to the new sound but you end up Wanting to listen to your music collection over and over.
