After montsh using the HD 650 I have to say that i think they are the best headphones ever, nothing to say, I felt in love with them in every sense, i love electronic music and the bass for an open can is tight and strong and amazing.
The details in the mid range and de highs that aren't harsh at all is like a design made just for my music taste.
Can be happier, i really think that the get better with 100/200 hours of burn in, i feel that the instrument separation gets wider and the bass punchier, Really noticiable for my ears.
I also own sony xm4, sennheiser hd25, Piooner HDJ X10 and v-moda m100, all those headphones are miles away from this in every aspect.
