For some reason I cannot write review.. So just to share my thoughts, I have these cans for a month or so, they are not definitely burn in.. I think it is great value headphone. I think HD 6XX is better in general on, because I have darkvoice OTL, but its different. AR is better in some areas like transparency and maybe will get better and better once more burn in is in the place. Now I have CTH tube hybrid and it sounds quite good.. Definitely quality is here. I will give 4 stars, because HD 6XX seems better to me in general so far especially on darkvoice, but lets see later on.. Btw its very good for gaming.
