After a few more listens, I would like to balance the book, these are the negatives (IMO)...
1) In order to create the 'room feel', there are 'echoes'... it is like a acoustic concert hall where you are at the last row, the voice sometimes will have waves of echoes behind them. This became very prominent when I listen to 'Rolling in the deep' by Adele, it will not appear the whole song, rather some of the quieter, more acoustic passages... but some of the other songs will not have it at all.... these is a unique feature and CAN be a make a break deal to some.... and you will only notice it ONLY when you give it a serious listen ....
2) These cans CAN isolate outside noise but they do leak, and the leakage is quite bad. If you are alone, you will have no problem blasting the volume, but if you are in a subway/Library and you do not want people to listen to your music, you need to adjust your music to low volume and even then, they still do leak...
However, the sounds that comes of these cans is so good, I am willing to forgive the flaws (for now)...
