Just got them today and unpacked. I will be listening to them in the next few days before I come up with my opinion on how they sound and also the difference between these the the Sony I returned after few days of listening.

My first impression is that it has a lot more oomph in the low end that I am used to with the HD-600 that I have had a long time. The separation of instruments is also there. Once you listen to the headset with aptx codec enabled source the sound quality improves a lot.

Allow me to give it a go for few days before I go into details and a more through evaluation.
